** Description changed: - Binary package hint: xorg + An X fault occurs in Ubuntu's automated testing facility across a range + of machines which shows itself as an Xorg segfault during the + installation process. I suspect it to be caused by an out-of-memory + situation. Perhaps a memory leak? - We're attempting to install from a Natty daily image, through the - network and using a preseed file. + We've been chasing this bug for a while (such as fixed in commit + 6e721e098b9181e8e77e314f966729d28e705582) but this is just fixing the + error handler not addressing the underlying cause. + + The issue is seen only on Intel graphics hardware and (often) results in + an X termination within the drm code. + + [Original Report] + 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. I've also observed the systems rebooting, my guess is that it happens when the bug gets triggered twice in a row (once for the installation and once again for the LiveCD environment). syslog shows a sefgault on Xorg, which is probably what's causing the installer to die. This particular trace and attached apport report were produced on a Dell Vostro 3400, though I am able to reproduce the problem on an Acer Aspire One D255, Lenovo Thinkpad X201, Asus EeePC 1001PX and Dell Inspiron Mini 1011. This bug is very similar to bug 708744 which is a duplicate of 705078, and the circumstances under which it occurs are as described on bug 706117, we're using the same test setup and the only thing we changed was the image, this problem occurs using the 20110207 image, and though the symptom is similar, from glancing at the backtrace I get the impression it's a different problem than the one described/fixed on bug 705078. How to reproduce: - Use the LiveCD image from 20110207 to do a network install using the attached preseed file. The system gets PXE configuration through DHCP and its preseed file via http, mounting the relevant install media through NFS. Expected result: - System finishes installing and reboots - Actual result: + Actual result: - The installation gets stopped when the X server crashes, usually dropping to the LiveCD environment.
