X crashed while browsing with Chromium (librecord.so related?)

[Herman Boomsma]

X crashed while I was browsing with Chromium.

I'm using a dual-monitor setup on a ATI Technologies Inc RV620 LE [Radeon HD 3450]. No changes made to xorg.conf. Using radeon driver.

Have you been able to reproduce this bug? What kind of media was Chrome trying to view at the time of restart? Flash? Streaming video/audio?

[Herman Boomsma (harmus)]

If I recall well a flash animation was loaded. I cannot reproduce the bug. I use Chromium all day and the problem has not reoccurred.

[Bryce Harrington (bryce)]

If you could reproduce it I'd have you collect a full backtrace, but since it appears to have been a one-time crash and has only a terse Xorg.0.log crash log, it's unclear what happened.

I notice you have virtualbox-ose installed, which has it's own driver modules. Perhaps it's doing something funky with librecord.

[Timo Aaltonen (tjaalton)]

this seems to be on real hw, not vbox. The trace looks similar to bug 771655.

[Bryce Harrington (bryce)]

Likely dupe of bug #774978

[Ondrej Certik (ondrej-certik)]

How can we get the full stacktrace for a bug like this? For me, it happens once every couple days (sometimes once a day, sometimes once a week). But I can't reproduce it on demand (i.e. while running X under gdb).

The only solution that I know if is to use a library like this (I wrote it):

https://github.com/certik/stacktrace

compile it with Xorg, and then wait. I didn't have time to do it yet, so I don't know if it is actually going to work.

Any help is appreciated.

[Marcelo Fernandez (fernandezm)]

I mark this as duplicate of #774978 since Albert Damen gave some advances into isolating the bug.

Status changed to 'Confirmed' because the bug affects multiple users.
