[i945] [i945] [i945gme] Xorg crash on a netbook (Intel video): Segmentation fault at address 0x400007c

[Antti Kaihola]

Binary package hint: xorg

I was typing in Emacs and Xorg segfaulted. The keyboard and mouse didn't work, and I had to hit Alt-SysRq-K to get back to the login screen.

I have an external display connected to the Mini 9 netbook, and I had previously toggled the active displays back and forth with the Fn+8 keys (over an hour before the segfault).

The netbook also suffers from bug #507813 and the symptoms were similar this time as well, but the backtrace in Xorg.0.log.old is different.

[This is an automatic notification.]

Thanks for reporting this bug to help making the Intel graphics driver
better. We hear from upstream that a number of bugs (possibly including
this one) have been fixed in the newer DRM code from the 2.6.33 kernel.
I don't know if your bug is one of the ones fixed in this release,
though, but we've prepared a PPA with this DRM update. Would you mind
installing this, rebooting, and testing if the original issue can be
reproduced with it or not?

The DRM PPA is here:

    https://edge.launchpad.net/~apw/+archive/red

Note there could be new bugs... please file these as new reports using
the command 'ubuntu-bug linux' (for kernel or DRM or KMS bugs) or
'ubuntu-bug xorg' if you suspect them to be X.org issues.

[Bryce Harrington (bryce)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
