seems like I got a serious kernel problem on my Fedora 16, 64bit.
Only yesterday everything worked just perfect. Today, after booting my
whole desktop froze a few seconds after the OS has been loaded.
After setting the runlevel to 3 (setting that symlink to multi-user.target that
is), I get the following:
[ 104.163.988] BUG: soft lockup - CPU#2 stuck for 22s! [kworker/2.2.81]
followed by a lot of traces and the same message in variations again.
I had a similar problem with kernel lockups a few weeks ago when trying
to install adobe reader via Adobe's yum repository, which I manged to solve back
then by removing the newly installed packages again. However, this time
I did not
install anything. The last entry in /var/log/yum.log is from Feb 9th.
The last thing I did, was to configure some test shares with samba.
I already removed all the samba packages, to no avail. It's not tied to
a specific kernel ... the latest one I have installed (3.2.3-2.fc16.x86_64)
produces the same problem as any earlier version and it's not the X server
(since the problem stays in pure text mode "runlevel 3" as well).
There's nothing in /var/log messages either. The system just works for about
half a minute as usual then hangs with this error. I can only assume that
something get's loaded after that time, that causes the system to freeze. Selecting
the rescue mode kernel in grub works but doesn't give me any more clues
either. CPU is an AMD FX-4100, with 8GBs of memory installed. Any hints
or suggestions on how I could trace this problem or provide more information
would be greatly appreciated, as I'm close to a nervous breakdown.
