Comment 47 for bug 1301839

xorg 1.15.1 stable, xf86-video-ati, glamor, mesa, etc. from relatively recent git.

Two GPUs in my laptop:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M] (rev ff)


Runs fine but slow on intel graphics, immediately crashes X on radeonsi. Other things run fine currently.

I don't see a backtrace written to Xorg.0.log which is weird. Later I'll maybe try to get a backtrace with gdb but this seems to be easily reproducable, so other people can try too.
