Description Bojan Smojver 2011-06-01 23:57:13 UTC

Description of problem:
Kernel OOPS in do_writepages, it seems.

Version-Release number of selected component (if applicable):
kernel-2.6.38.6-27.fc15.x86_64

How reproducible:
Once thus far.

Steps to Reproduce:
1. Not sure, but this machine was hibernated/thawed twice. With F-14 kernels, there used to be all kinds of hibernate/thaw problem, so maybe it's related. Just sayin'...
  
Actual results:
OOPS.

Expected results:
No OOPS.

Time for a reboot. This stinks of hibernate/thaw issues from the past...

Comment 2 Dave Jones 2012-04-11 16:56:35 UTC

I wonder if this is another case of the i915 corruption problem ?
Still seeing this at all ?

Comment 3 Bojan Smojver 2012-04-11 21:55:15 UTC

It is. Sorry, I was just lazy to close such bugs that I had opened.
