Xvideo errors on RV710 "timeout going to reset GPU" with 6.13.0 and recent kernel versions

[Marco Schinkel]

Hello,

as of recently I cannot use Xvideo on my RV710 PCI card anymore.
I updated to X.Org X Server 1.8.0 with xf86-video-ati 6.13.0, recent
libraries and 2.6.33.2 kernel (tried 2.6.34-rc4 too, same problem).

Normal X display works without problems, but as soon as I start vlc or
mplayer with Xvideo output the picture hangs or gets corrupted (black
screen, some coloured line at the top). There are no messages in the
Xorg log but the kernel spits out the following (repeating every few
seconds until I stop the X server):

Unfortunately I cannot interprete this completely. The RV710 is on a PCI
card (not PCIe). I wonder if the timeout may be too low or something
similar. The card is used for playing videos and only connected to a
projector and running as single card, single screen with a dedicated X
server.

The RV670 used as primary card with two LCDs works perfectly with Xvideo
on the same Kernel/Xorg/Driver versions, so it is not a "recompile with
the newer libraries" problem. The same setup worked really nice with
some git version before 6.13.0 and 2.6.32 kernel.  Does anyone have an
idea on how to fix this?

Thanks,

Marco
