OT: A note to the person in the next cubicle
by Bill Case
Hi;
I know -- a too cutesy subject line.
But I wanted to make the point that the following subjects are not
critical to me; just things I am wondering about as I get ready to
install Fedora 11. I work at home alone. Most of the points are of the
type I might bring up over coffee with the guy in the next cubicle, if I
had a guy in the next cubicle. If you are doing something important
(like earning money) and don't need a break just ignore this post.
#1 Upgrade vs LiveCD fresh install
I am trying to make up my mind whether I should do a fresh install from
the LiveCD or upgrade. I have always done a full .iso download and new
installation in the past. I thought I would try something new i.e.
LiveCD or upgrade.
My hesitation on choosing to upgrade is that by just upgrading I might
not get some of the fixes I am hoping for. In particular, in F10 to get
my TV tuner working I had to install new firmware and modprobe the
'tuner' module. I never did get the sound working. From this list and
others, I have come to understand that the kernel in F11 has all the
modules I need compiled in and that PulseAudio can now handle the sound.
I will leave further details for a separate post if the TV is still not
working.
I just want reassurance that by upgrading I will get the same fixes as
by a virgin install.
#2 A Bug vs a Nitpick
With each new release there are an expected number of bugs that show up.
I am not complaining, that is part of the deal when using Fedora and I
am happy to file a bug report whenever I can. But sometimes there are
things that are wrong that are, to me, more of a Nitpick than a bug. I
am often reticent to use bugzilla for something that is minor and has
more to do with look and feel or smooth operation or a manuals
usefulness than being broken. I don't want to be a PIA by constantly
nitpicking, but on the other hand I would think that developers would
like help in getting it exactly right. Any thoughts?
#3 Finding bug citations
I have noticed that when experienced users respond to a question/problem
on the users list their response often contains a link to the
appropriate bug. When I google to find a solution to something google
never (seldom) returns a bug link. Are people doing something (using
special search criteria) to search the bug database at the same time as
a general google search or are they doing a separate search in RedHat
bugzilla or do they just recognize the problem and give the link to the
bug covering it?
#4 Giving back help on the users list
I have been using Linux/RedHat/Fedora for over four years. I have
received a lot of constructive help from users mailing lists.
(In fact, as hard as it may be to believe, I have become the computer
guru amongst my small group of retired friends. Although most of the
problems are M$ related, we manage to get most people going again.)
I often recognize problems brought up on the Fedora users mailing list,
and have the sure-fire solution while others respond with solutions that
are terribly wrong. However, I am often reticent to help because too
often I have seen that my 'sure-fire solutions' are wrong or
unprofessional and too many of the 'terribly wrong' answers have, of
course, been right.
I would like to give back. So ... what kind of mind query or problem
analysis do effective responders use before giving info to other users?
#5 Fedora 11 LAN installation
I have a two computer (sometimes three computer) LAN in my house. Both
are F10 to be F11. In the past, to keep it simple, I have installed the
newest Fedora version on each machine by burning the .iso to disk(s) and
then doing two separate installs. I was thinking that this time -- just
for the hell of it -- I would do something fancier like install F11 on
the second machine using the LAN.
The problem is: I have never used the LAN for anything real before. I
got the LAN connection up and working and that was about it.
I am not looking for details -- I can read. But a quick perusal of the
Installation Guide has left me a bit confused with too many options. A
quick (short) list of what I should be looking at would really shrink
the learning curve.

kernel:Disabling IRQ #23
by Lars Kunert
Hi,
yesterday evening I lost the ssh connection to my server,
the last message was:
> Message from syslogd@guest-195 at Jul 4 23:29:08 ...
> kernel:Disabling IRQ #23
I could not renew the connection. After a reboot I found the following
messages in /var/log/messages (attached below)
The server contains 10 harddisks
- 2 SAS drives connected as SAS drives
- 6 SATA drives connected via SAS, and
- 2 SATA drives connected via SATA
Do these messages point to a single harddisk as the source of the problem?

Files corrupt on copy
by Andy Campbell
I'm having an issue where when I copy files, they are not copying
correctly - they are corrupt, I've checked using cmp, and generating
md5sum There are no errors I can see from cp, rsync.
Initially I though it was a problem with an external USB drives now
after some testing it seem to be normal SATA drives as well. I've got
a few drives in the box and they all have the same issue.
I thought it might be memory - but memtest runs fine, and I
tried taking out a couple of the sticks - I have 4x2Gb no difference.
I've written a little rsync script to copy some files around, rsync
once, then rsync again, using checksum - in theory the second run
should have nothing to do, but will randomly have to re-copy files.
Strangely I tried booting off of a live distro ( System Rescue 32bit )
and didn't get any errors.
The system seem to run fine generally - but I started noticing some of
the big files I was syncing to external drives where erroring. Just
repeatedly running md5sum on a file gives consistent results - I would
have though if was a memory problem that would have give different results.
I've turned AHCI on in BIOS recently as I've install a WD Raptor,
and re-installed F10 - would that affect filesystems on other
drives - is AHCI buggy ?
I'm using Fedora 10 64bit, Asus P5Q-E Motherboard,
Q9950 ( stock speed ), 8Gb Corsair memory
Any guesses, Kernel bug ? Hardware ? Hopefully not hardware as its
a fairly recent build.

Nfs permissions problem -
by Bob Goodwin
Can anyone tell me how to enable user "bobg" to access the nfs server on
my box48?
At the rate I'm going I will have all the permissions set to 777, will
need a new install to get them back where they ought to be.
[bobg@box9 ~]$ ll -al /mnt/home
ls: cannot access /mnt/home: Permission denied
[bobg@box9 ~]$ cd /mnt/home
bash: cd: /mnt/home: Permission denied
[bobg@box9 ~]$ ll -al /mnt/home
ls: cannot access /mnt/home: Permission denied
Nfs works fine as route but I haven't been able to find why permissions
wont allow a user access. Both are running F-10 and up to date.
I really need some help on this.

wrong gearing on F-10
by Arne Chr. Jorgensen
Hi,
Still having trouble with Fedora-10 and the machine halt
if I don't hold a finger on the touchpad. That is, recent
kernel works somewhat with "nomodeset".
Machine Turion64X2 and RS690M chipset, and running Radeon.
It is configured as SMP, and here is my question:
- How can you run glxgears in reverse ? How does threading
work ?
I have had it running in reverse, and I have had it jump back
and forth a few cogs.
Now, we have had Xorg using a lot of CPU power, not really
producing anything but heat. But if treads jump back and forth,
could not something like this explain it ?
Can anyone shine some light upon the subject ?

Logged in twice?
by gilpel@altern.org
This aft, I notice the HD was flashing all the time and I wanted to see
what kept it busy.
The first thing I noticed with "top", is that there are two users. Issued
the command "users" and saw my user name twice. Looks like I'm logged in
twice. Why is that?
The only process I couldn't figure out that was at the top of "top" was
multiload-apple(t-2). "free" shows that buffers are increasing by 8 KB
each time the light goes on. This seems somewhat related to Firefox
running. It persist some time after it's closed, than stops.
Why are the buffers increasing when I don't use Firefox? (It's just open.)
Note: I have the System Monitor applet installed and the page on its
configuration is:
http://gnome.gr/wp-content/uploads/2009/05/documentation_gnome-applets-mu...
but multiload appears nowhere in the document. In case this would help.

Error: on reboot after upgrade to F11 ??
by Bill Case
Hi;
I have just used preupgrade to upgrade from F10 to F11. Everything went
fine until 're-boot'. Anaconda (I believe) gave me the following error
message:
"The following are directories which should be symbolic links. Please
return them to their original state as symbolic links and restart the
upgrade.
/usr/tmp "
On checking, /usr/tmp IS a symbolic link, linked to /var/tmp which shows
empty.
What now?

configure phonon with no kde
by oleksandr korneta
Fedora 10 i386. I'm playing with minitube
(http://flavio.tordini.org/minitube). I have no kde installed and this
is the only application for which I had to install phonon (along with
phonon-backend-xine and phonon-backend-gstreamer). qtconfig-qt4 says
that phonon is not available, but the minitube got sound already, so all
I need works. However, minitube blocks the sound output while running,
which makes me think that audio sink is set to OSS. The question is How
do I configure phonon without installing the whole KDE if qtconfig
doesn't see it?

regards,
Oleksandr Korneta
I'm running F9 x86_64 and F10 i386 on x86_64 hardware, should this matter.

f11 - ext4 and encryption fails to create /dev/mapper/luks-xxx
by Genes MailLists
Is this known to work or not work ?
I just tried a clean install of f11 with encrypted swap, and /home.
Install went ok - cmputer rebooted and got error - failed to locate the
/dev/mapper/luks-UUID for the encrypted /home.
The luks stuff is there and fine - verified by running luksDump
and also by cryptsetup luksOpen by hand. After which I can mount
/dev/mapper/xxx no problem.
The Boot fails however as clearly the luksOpen failed or was not called
correctly and so /dev/mapper/xxx is missing. The swap /dev/mapper/yyy is
created so that went fine.
/etc/cryptab and fstab all look fine - and dmesg has no info.
Anyone know if I can make this work somehow ? Certainly exncryption
with ext3 under f10 worked no problem).
Appreciate some help ?
thanks.
