Feel free to reassign/close, since everything's fine with the 2.6.32-28 kernel. I'm not convinced it's a kernel problem, because I'm fairly sure (but not certain) that I had used successfully used virtualbox at some point before my previous reboot. That is, I *think* that I had managed to avoid the crash at least once when running 2.6.32-27. But I can't easily confirm that now. --scott -- ( http://cscott.net/ ) -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

Bug#606372: Hard power cycle fixes it.
A power cycle (power off, power on) fixes the crash. Restarting just X didn't fix the problem; reverting to xserver-common_2%3a1.7.7-9_all.deb, xserver-xorg-core_2%3a1.7.7-9_i386.deb, xserver-xephyr_2%3a1.7.7-9_i386.deb, and xserver-xorg-video-intel_2%3a2.13.0-2_i386.deb also didn't fix the problem. My diagnosis is that this is a not-recent bug in initializing the GPU -- the GPU can get into some funny state that the current init code can not fix, and which will cause a later segfault in the DRI code. *However* another possibility is that rebooting changed the kernel version. The logs from the bug I submitted above say the kernel was: Linux version 2.6.32-5-686 ... Sat Oct 30 22:47:19 UTC 2010 which corresponds to debian version linux-2.6 (2.6.32-27), and my current running kernel version (which doesn't show the bug) is: Linux skiffserv 2.6.32-5-686 ... Thu Nov 25 18:43:34 UTC 2010 which corresponds to debian version linux-2.6 (2.6.32-28). I will try to downgrade the kernel to determine which of these theories is correct. --scott -- ( http://cscott.net/ ) -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
