Comment 4 Zdenek Kabelac 2009-09-16 09:12:00 UTC
Interesting - that I'm getting similar backtrace with Intel 

I've originally though it's 'standard' Intel GPU problem (and as such I've resigned to report these issue anymore...) - but when I see that same happens with Radeon - it looks more like design issue in the DRM.

The crash usually appears when I resume system and I play for a few minutes with it - like moving mouse over firefox - suddenly system stops to respond - except mouse keeps moving - everything else is dead on my display.

Looks similar to this post:

http://linux.derkeiler.com/Mailing-Lists/Kernel/2009-09/msg04062.html

This trace is from end of August with rawhide packages from this time.

[mi] EQ overflowing. The server is probably stuck in an infinite loop.

Recently I've noticed on the kernel list that there was  potentially wrong code for resume on i915 agp drive - not really sure if this is connected/applieable to my i965 - so I'll wait if it will lower the amount of my resume problems.

Comment 5 Bug Zapper 2009-11-16 09:42:22 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

More information and reason for this action is here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 6 Vedran Miletić 2009-11-16 14:20:16 UTC
Updating summary.

Is this really a kernel bug?

Comment 7 Bug Zapper 2010-11-04 11:37:57 UTC
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 8 Bug Zapper 2010-12-05 07:04:43 UTC
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

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

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