Hello Alexander,

So, it turns out that it is not so easy to reproduce this issue. I
have been trying to reproduce it with the exact revision of 3.10-rc7
where I first encountered the problem but with no luck. This of course
has hampered my bisection since I cannot be sure which revisions to
mark good/bad. Do you have any suggestions in this regard?

I however have a UVD-related lockup that I can always reproduce on
3.10-rc7: Trying to use UVD with the command: "mplayer -vo vdpau -vc
ffh264vdpau test.mp4" _always_locks up the same system (same kernel,
same DRI stack) hard. I will report this in a separate email, though
nothing at all shows up in the logs for this latter problem due to the
hard lockup. Suggestions about how to help debug this are also
welcome.

Many thanks.
