This is with kernel-2.6.20-1.2944.fc6.  The last thing I did was to run
"locate", though I doubt this is related since I use that command quite
frequently without any problems.  I stopped using ndiswrapper a few weeks back,
and uninstalled it and all its kernel modules.  I'm now using cat-5 cables
strung around my apartment, so this oops is not related to the wireless
subsystem.  There do seem to be other kernel oops reports in bugzilla which are
related to sleeping the system.  I have used "suspend system" today, but that
was several hours ago.

After this oops, I was unable to start any new applications (emacs,
gnome-terminal, etc.), so I was forced to reboot.  I was able to paste the text
of the oops into an open Emacs buffer and save it to disk, which is how it is
reproduced here.

Comment 1 Jon Stanley 2008-01-08 01:54:16 UTC
(This is a mass-update to all current FC6 kernel bugs in NEW state)


I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.

I am CC'ing myself to this bug, however this version of Fedora is no longer

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!

Comment 2 Christopher Beland 2008-01-23 22:03:03 UTC
I haven't experienced an oops with this particular trace with Fedora 8, though I
have reported other oopses in separate bugs.

Comment 3 Christopher Beland 2008-01-23 22:11:41 UTC
You might want to see bug 428329; I suspect there might be a general problem
when I suspend/hibernate which results in a variety of kernel crashes.

Comment 4 Bug Zapper 2008-04-04 07:06:54 UTC

This bug is open for a Fedora version that is no longer maintained and
will not be fixed by Fedora. Therefore we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen thus bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
