Description Christopher Beland 2007-09-19 17:29:56 UTC 
Today I experienced a kernel eeek with kernel-2.6.22.6-81.fc7, which
is currently posted to updates-testing.  There was the following
sequence of events:

* Disconnect Ethernet cable, mouse, and power cable to go to meeting.
* Close laptop lid, laptop goes to sleep.
* Open laptop lid and press power button to wake up laptop.
* Emacs window is not redrawing; found Eeek! message in gnome-terminal window.

I will attach log output.

Comment 2 Dave Jones 2007-09-19 17:42:12 UTC 
before digging into this one any further, does this machine survive a run of
memtest86 ?

A few cases where this has been hit before have been down to bad memory or other
hardware failure.
Comment 3 Christopher Beland 2007-09-19 19:49:23 UTC 
memtest86 v3.3 finds no errors.

Hello,

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

http://fedoraproject.org/wiki/KernelBugTriage

I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
Comment 5 Christopher Beland 2008-01-23 22:14:18 UTC 
I haven't experienced an eeek with this particular trace with Fedora 8, though I
have reported other oopses in separate bugs.  I'm beginning to suspect there
might be a general problem when I suspend/hibernate which results in a variety
of kernel crashes.  (See bug 428329.)
Comment 6 Christopher Brown 2008-01-23 23:01:55 UTC 
Hmm, okay. I'll update to Fedora 8 and close as CURRENTRELEASE but please
re-open if the eeks come back. Thanks for filing...
