Xorg.log

I'm running Arch linux and after I updated and rebooted due to kernel 3.10
hitting the Testing repository I've experienced many X.org crashes du to bus
errors.

I've attached both my X.org log file and a dmesg output.

The crash it self happens (seemingly) random, but after the first crash it
crashes again right after I log into KDE. Probably when desktop effects are
started.

I have a Radeon HD 5670 card, and I run mesa from git with daily updates. I've
also tried out the new UVD acceleration and got the error that is displayed in
the kernel log.

What version of mesa are you using?  You need to build the r600 vdpau driver in
mesa to use UVD.  As for the crash, can you bisect?

I'm using mesa from git. (Right now: g4dbca86). I'm not able to bisect right
now (I'm at work), but I'll give it a shot next week.

I'm suspecting VDPAU/UVD, because I tried to used it with adobe flash due to a
red and blue color swap and I got this error after a while: 

[drm:radeon_uvd_free_handles] *ERROR* Error destroying UVD (-22)!

And vdpauinfo stopped showing h264 and all the others, I was just left with
MPEG2-variants (possibly the shader decoder?). After a reboot I was able to see
all the supported codecs again.

I've now disabled the hw-decoding in flash to see if the crashes go away.

It's probably not a kernel bug then.  More likely a bug in the 3D or vdpau
driver or in flash.  I just happens to manifest on 3.10 since that was the
first kernel with UVD support.  If you can narrow it down to flash or UVD, you
may want to close this bug and open a mesa bug (https://bugs.freedesktop.org)
against the r600 gallium driver.

With no usage of UVD, I've not seen this bug for the entire weekend, so I'll
close it and reopen one against the gallium driver.
