...hine is otherwise working mostly ok so I can ssh to it. The "issue" I have is that there is nothing interesting (afaict) in any log. Nothing in Xog.0.log, nothing in dmesg. The one intersting thing I've noticed is that with drm debuging on I get a ton of these on dmesg: host [drm:drm_ioctl], pid=2391, cmd=0x40086485, nr=0x85, dev 0xe200, auth=1 And at, or around the hang, there seem to be a an increase of: host [drm:drm_ioctl], ret = fffffff5 Not particilarly enlighening to the uninitiated. Any ideas how to debug these hangs? Are ther any tools around to e.g. reset the GPU? /An...

Hi, I''m trying to get secondary vga-passthrough on a HVM guest to work with a AMD HD6570 and the native kernel radeon driver and kernel modesetting. So the guest still gets the emulated stdvga or cirrus device(used in my case here) as primary/boot vga adapter. - When i don''t passthrough the radeon card, the
