Red Hat Bugzilla – Bug 829003
kernel panic & machine lockup
Last modified: 2013-07-31 13:44:43 EDT
Description of problem:
I have a Lenovo x220T which uses the intel i915 kernel module. I had it in my docking station connected to an external monitor in a two-screen layout in GNOME shell. I was typing some text in a design in Inkscape, suddenly everything froze. The external monitor blinked black for a second and immediately came back. The system refused to accept any input, the screen remained frozen moving the mouse did not move the pointer, none of the TTYs worked either (no response to keyboard input.)
/var/log/messages appears to indicate that the GPU hung. from /var/log/messages:

The system had been up for three days, having been suspended and unsuspended and used both on and off a docking station. I don't know if this is relevant. I installed F17 fresh the week of release so I haven't had the system that long; this is understandably difficult to reproduce but if there are any logs i can grab that would be useful let me know.
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. 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bug reports from releases that are no longer maintained.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 '17'.
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 17'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 17 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, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
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.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 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no longer maintained, which means that it will not receive any further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.
