Description Benoit Jacob 2010-12-08 14:49:01 UTC

This is, like bug 32238, comes from https://bugzilla.mozilla.org/show_bug.cgi?id=616416

In the same situation as in bug 32238, when the user switches to software rendering, he gets a crash too, but this time it's a SIGABRT with a different stack:

Program received signal SIGABRT, Aborted.

Comment 1 Brian Paul 2010-12-08 15:41:29 UTC

Can you test with a debug build and gdb?  It would be good to know the buffer->Width and buffer->Height values.

Comment 2 Octoploid 2010-12-08 20:27:19 UTC

As I wrote on the mozilla bug:

I normally use my monitor in portrait mode:
DVI-0 connected 1050x1680+0+0 left
When I rotate it back to its default position and run
"xrandr --output DVI-0 --rotate normal" there are no
crashes anymore and webgl is working fine.

It seems as though that the RS780 microcode didn't
get loaded at boot-time on the kernel I was using
during the tests:

Notice that the line: [drm] Loading RS780 Microcode
is missing. I've checked my kernel logs and this was
the only time it didn't get loaded during boot.
(I don't use modules, everything is build in)

I don't know, could this be the reason for the bug I
was observing?

Comment 4 Octoploid 2010-12-12 04:11:36 UTC

I cannot reproduce the problem anymore, so I'm closing this bug.
See the mozilla bug for more info.
