Why does FC6 client become unresponsive during NFS write operations?
by Nick Thompson
My FC6 desktop client becomes unresponsive every 15-30 seconds for 5-15
seconds during long NFS write operations. My installation is up-to-date as of
this morning. This occurs with both an FC4 NFS server and another NFS server
I have running nfs-utils. I can't see any issues in nfsstat on the client:

Any ideas what I can look at? I need to get NFS running for home directories,
but the machine using it become unusable when copying big files around.
Thanks,

How to add /sbin to useable paths on FC5
by Nigel Henry
I have a problem when compiling a library. I am upgrading Aldrin, a music app.
The latest version needs a library that used to be integrated in Aldrin, but
now needs to be installed separately. The library "libzzub" doesn't seem to
be available for FC5, at least not in extras, or freshrpms.
This library is built using scons, but when I su to root to do a "scons
install" it insists on running ldconfig, which it can't as it's not
calling /sbin/ldconfig, and lunches out saying there's a problem.
I had a look in /etc/profiles, and I'm sure on an earlier version of FC, I
added /sbin to the paths, but FC5 seems to be a bit different.
What do I need to do, so that it is not necessary to call ldconfig
as /sbin/ldconfig?
/etc/profiles on my FC5 install is below.
# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
pathmunge () {
if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)" ; then
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
fi
}
# ksh workaround
if [ -z "$EUID" -a -x /usr/bin/id ]; then
EUID=`id -u`
UID=`id -ru`
fi
# Path manipulation
if [ "$EUID" = "0" ]; then
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
fi
# No core files by default
ulimit -S -c 0 > /dev/null 2>&1
if [ -x /usr/bin/id ]; then
USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"
fi
HOSTNAME=`/bin/hostname`
HISTSIZE=1000
if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
INPUTRC=/etc/inputrc
fi
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC
for i in /etc/profile.d/*.sh ; do
if [ -r "$i" ]; then
. $i
fi
done
unset i
unset pathmunge
What does "pathmunge" mean?
Thanks for any help with this problem.

Swappiness...

Re: /proc/acpi/ibm/dock disappeared

Actually I don't... I just press the undock key on the docking station
(this activates some actions in my acpi script, including the echo on
the dock file) and undock... The last time everything seemed to work
correctly even when docking again. Don't ask how!:-)

Alberto

Gnomestartup log on FC6
by Styma, Robert E (Robert)
Every since going from FC4 to FC6 the window
manager does not start all windows from a
saved the session. The $HOME/.gnome2/session
file lists all the programs to restart, but
they do not all restart.
The /var/log/Xorg.0.log does not have anything
interesting. Does the window manager used
with Gnome store a startup log anywhere and
are there debugging options which can be used?
I have not found anything useful so far.

/proc/acpi/ibm/dock disappeared
by Alberto Ferrante
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
Dear all,
I have been running Fedora Core 6 on an IBM/Lenovo T60 laptop for a
couple of months. From the advent of the 2.6.19 kernel the file
/proc/acpi/ibm/dock have disappeared. This file is used to dock/undock
the laptop on the docking station. For some reasons docking and
undocking seems to work correctly in any case, but I have had no time to
do extensive testing.
Is anybody else having this problem?
Regards,
Alberto

Grub stage2Read error
by Jeremy Nix
I've read about other people experiencing this problem but I have yet to
find a definitive fix. Below is my hardware and setup configuration.
I've tried on other Linux Distributions as well as other boot loaders
(lilo), but the result is still the same, failure to boot after
install. Like similar posts, I can get fc6 to install and run if I pull
out the Adaptec card and install, but that really doesn't help me out.
I've tried mucking around with the BIOS configurations with no luck...I
did make sure that the device order was Perc 3/di, then Adaptec. I've
even tried turning off the BIOS in both the raid controller configs, but
that really didn't improve my situation. I'm beginning to think that
the only way to get Linux on this box is to use only a single raid
controller to control both the internal and external disk array. I'm
not a hardware expert, but I'd imagine that the performance of 2 raid
controllers is greater than that of 1.
If anyone has a clue, feel free to pass it along.
Hardware:
Dell PowerEdge 2650 w/ Perc 3/DI Raid controller (5 73GB drives)
Additional Adaptec 2120S Raid Controller linked to PowerVault 220S (4
173GB drives)
Raid Config:
Perc 3/DI: 1 plain volume (1st volume), 2 sets of mirrored volumes
PowerVault 220S: 1 raid 10 volume.
Partitioning:
/boot and SWAP on plain volume
/ on 1 mirror
/opt/pgsql/log on other mirror
/opt/pgsql/data on raid 10

ivtv and kernel 2.6.19-1.2911
by Colin Brace
Hi all,
In the course of some recent upgrades, my PVR150 card is no longer
recognized in my FC6 system. I've updated the ivtv-related packages to
the latest versions:
rpm -qa | grep ivtv
ivtv-0.10.1-126.fc6.at
ivtv-kmdl-2.6.19-1.2911.fc6-0.10.1-126.fc6.at
ivtv-firmware-20070217-13.at
but for some reason ivtv won't load:
# modprobe ivtv
FATAL: Module ivtv not found.
Since installing the PVR card six or so months ago, I haven't paid
much attention to it; it pretty much just worked up until I installed
kernel 2.6.19-1.2911.
Anyone have any idea what has gone wrong here?

Firefox-bin gets killed by kernel?
by Colin Charles
Hi!
This happens on FC6/x86_64. I've not been able to repeat it, which is
why I've not filed a bug report, but I was wondering if anyone else has
seen this
Firefox basically crashed, and when I checked /var/log/messages, I saw:
Mar 5 20:13:09 hermione kernel: firefox-bin[19304] trap stack segment
rip:3b00a688d0 rsp:7fffed1d3890 error:0
Any idea why this happened?

Sun T1000/T2000 & Fedora/RedHat Linux
by Aly Dharshi
Hello Folks,
I hope that you are well. Recently looking at Sun's site under Linux
servers and was surprised to see that the T1000/T2000 was listed. Turns
out that Ubuntu and Gentoo have a version of their distros for this
(http://www.ubuntu.com/sun). Sun seems to have certified them for us.
Canonical will provide support (commercial) for these systems too.
Is there something in the works for Fedora ? Would the Ubuntu work in
this area benefit the Fedora folks ? Will RHAS version X support this at
a later date (not to distant future) ?
Cheers,
Aly.
