Xorg segfaults during installation process - X (CompositePicture+0x22b) [0x811822b] after bunch of intel_uxa_prepare_access: bo map failed

[Daniel Manrique]

Binary package hint: xorg

We're attempting to install from a Natty daily image, through the network and using a preseed file.

The installation starts normally and goes up to a certain point, but then the installer exits and we're dropped to the LiveCD graphical environment. Sometimes a "system program failed" message appears.

syslog shows a sefgault on Xorg, which is probably what's causing the installer to die.

This particular trace was produced on a Dell Vostro 3400, though the problem has been observed on other machines as well.

The installation worked before: the last known good image we tried was from 20110112. The first one where we observed this problem was 20110119. We also tried 20110120, 20110121 and the latest one today (2011-01-27).

This bug is related to #706117 (filed on Ubiquity), which also includes more detailed information on setup and steps to reproduce, as well as some more logfiles from affected machines.

This bug relates to bug 706117 (just fixing the LP link ;-) )

Bryce, it seems that the fix for bug 705078 is not enough.

We keep seeing crashes during the installation process. Could you please have a look? Thanks!

[Bryce Harrington (bryce)]

Please provide either a full backtrace or exact steps to reproduce the issue (or preferrably both). I am unable to reproduce this issue with the alpha-2 cd on 2 different systems I have at hand.

See http://wiki.ubuntu.com/X/Backtracing for directions on obtaining a full backtrace.

[Bryce Harrington (bryce)]

Alright, best guess is this looks to be the same as bug 705078, which I was able reproduce on my own hardware.

I'll dupe to that bug, undupe if you find I'm wrong.
