backtrace from gdb

Comment 5 Lubos Kocman 2011-03-17 21:56:12 UTC
100% percently reproducible on my setup. Happens immediately or after next refresh of the page.

I'd like to mention that the attached plugin is 64bit flash player square.

Anyway don't blame Mozilla plugin for Crashing Xorg

Comment 7 Lubos Kocman 2011-03-17 22:34:02 UTC
Does not seem to be actually very specific ... I just tried few other youtube vids and I got the same result.

Comment 8 Matěj Cepl 2011-03-17 23:32:49 UTC
Could we get also output of dmesg and /var/log/messages AFTER the crash but before reboot, please? I don't see anything interesting in the /var/log/Xorg.0.log.
