I am also seeing this on a foxconn nt-a3500 that has a radeon hd6310 - part of
the amd fusion. If you want additional information, let me know.

This patch reverts to the original behavior, just to make sure that it's indeed

Raise UVD clocks while booting the VCPU.

>I've already tested this by myself and can confirm that this fix the problem.

Ok then let's try to narrow this further down. The attached patch should tries
to only raise the clocks while the VCPU is booting.

Please test on your hardware.

It's related to the [PATCH] drm/radeon: raise UVD clocks while booting the VCPU
patch. With this applied, X crashes when starting chromium browser.

I don't think that crashing X is related to a not working UVD ring, at least it
shouldn't.

Anyway, I've got a good news: I was able to reproduce the problem with a
HD5670, so a final patch fixing this is on the way.

I can only say what I'm observing. with this patch X crashes as soon as I start
chromium. Without it doesn't.

Sounds good, I'm waiting for testing.

  --> https://bugs.freedesktop.org/attachment.cgi?id=78377&action=edit
Possible fix

This one should do it, the problems indeed seems to be that the VCPU on
evergreen doesn't work with the lower clocks.

Please test.

and no errors, video playback with UVD (mplayer) works and no crashes with
chromium. Perhaps the crash with the last patch came from the flash plugin that
tried to use VDPAU/UVD? Anyhow, it works now. Feel free to add my tested-by.

Thanks for testing, good to know that it fixes the problem.

The comment about flash sounds valid, but I still don't get why the heck that
should crash X.

Anyway this bug seems to be fixed, please open up another one if you can
reproduce the X crash with the newest drm-next-3.10.

Ugh, wrong status and wrong bug looks like. I will leave this closed and
comment on 63935 which seems more appropriate. Sorry about the noise.
