Article at 2CPU.com - Linux 2.6 and Hyper-Threading
by Marc Schwartz
Hi all,
Just as an FYI to the group, the following article is new at 2CPU.com:
Linux 2.6 and Hyper-Threading
http://www.2cpu.com/articles/ht_linux/
The final paragraph:
"The final word on Linux and hyper-threading? While the majority of
benchmarks we've looked at here today have shown improvements, it's
still important that you do your own testing with the applications you
use on a daily basis. On the surface, HT certainly looks promising but
it's clear that there are still situations out there where HT is going
to negatively impact the performance of an application. Before rolling
out those new workstations or servers, do your own testing in
pre-production to find out what hyper-threading can do for you."
Enjoy,
Marc Schwartz

2.6.1-1.65 crash/burn repeatable
by Neal Becker
I am running 2.6.1-1.65 (last kernel I can test) on reiser/lvm2 (yes I'm
brave/stupid).
Every time I fire up amanda the system eventually freezes. AFAICT, it is
running tar at that time.
There are no clues in /var/log/messages.

Re: where to announce and discuss test updates (Re: Fedora Core 1Test Update)

fedoranews.org has an rss feed for the released updates already.
In fact the update rss feed is even part of the Fedorapeople blog
aggregate: http://fedora.linux.duke.edu/fedorapeople/
An rss feed for the test announcements would be harder, and would i
think involve more human effort. I'm pretty sure fedoranews is creating
their update rss feed from the fedora-announce-list which is just for
released updates announcements, the low traffic nature of that list
makes it much easier to regenerate announcements as an rss feed.
Someone needs to approach the fedoranews.org maintainer about creating
an rss feed for the test annoucements as well. And that someone should
be prepared to volunteer their time actively watching the
fedora-test-list for the test announcements and compiling those notices
into something that can be rss'd.

kernel-2.6.3-1.100 reiserfs ok, shmat strangeness (invalid arg)
by Bernhard K. Weisshuhn
Hi *,
The sleep_on() dependency of reiserfs seems to be gone now, thanks Dave!
But something seems to have changed wrt shm: After booting the prebuild
smp kernel all applications failed on shmat(). Logs say something
like this:
shmat(id=229378) failed: Invalid argument
After I compiled my own kernel from the same sources
(kernel-source-2.6.3-1.100), the problem went away. Everything runs
smooth now. Strange, huh?
Anyone want my .config?
cheers,
Bernie

Mozilla crashes with latest rawhide updates
by Mike Chambers
Anyone else seeing Mozilla just close when viewing certain sites (espn
is one of them) with the latest rawhide updates? No, mozilla was not
one of the updates.

Re: Wierdness with Internet
by Jim Shepherd
I possibly have the same problem. I installed Fedora Core 2 Test 1 and
had no problems with network connectivity, even after running yum
several times to update the packages. Today, I updated again and now I
can only access internet sites on the other side of my home router
(Wireless Linksys) by using the actual IP address, name resolution
fails. My other computer on the home network running RedHat 9 still has
full network connectivity.
I also tried disabling ECN: I logged in as root, typed:
echo 0 > /proc/sys/net/ipv4/tcp_ecn
and still had the same problems. I even restarting network services
after disabling ECN without success. I also checked resolv.conf and it
is the same as the RedHat 9 computer. Any ideas?

Re: Still Problems/Solution with Discovery of Creative Labs/Ensonic PCI 1371 Card.
by Peter Banks
Just for grins, (being unemployed I have lots of time) I deleted the hwconf
file in /etc/syscconfig directory and the lines in the modprobe file to
determine if kudzu would properly discover my Creative Labs/Ensonic PCI
1371 Card. (I update my Fedora system everyday.) Now kudzu selects the right
driver in the "alias sound-slot-0 snd-ens1371" statement but the install
sound-slot-0 state does not load the driver.
After a lot of attempts to get the line to work, I gave up and loaded the
following two lines in the /etc rc.local file:
modprobe snd-ens1371
alsactl restore
Works great!

Perl/mod_perl test update
by Chip Turner
Hey folks,
A perl and mod_perl update have been placed into testing. The goal is
to releasse perl 5.8.3 into FC1 by Friday, March 5th. The update
should be fairly smooth, but please test against all of your weird
perl modules (and especially with anything that embeds perl itself)
and note any breakages via bugzilla. All perl modules and apps that
embed perl should work properly. Apps known to embed perl that ship
with Fedora: gaim, vim, xchat2, mod_perl (part of this update).
Thanks,
Chip
