           Summary: Radeon UVD error
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All

I had this on occasion but couldn't reproduce it reliably:

Go to:
http://global.burton.com/on/demandware.store/Sites-Burton_GLOBAL-Site/default/Team-Riders

and move the cursor over the faces.

You will see many (toooo many) errors like the one below in the journal:

What browser do you use? Do you have video acceleration enabled in flash?

It sounds like flash is trying to play a lot of videos at the same time.

I observe the same issue on virtual machine with VGA passthrough. The virtual
guest runs only Kodi media center session with autologin from lightdm display
manager.
The issue is easily reproducible when I do fast forward (FF).

Here's sample from dmesg:
[  195.123895] perf interrupt took too long (10006 > 10000), lowering
kernel.perf_event_max_sample_rate to 12500
[  457.994431] perf interrupt took too long (20020 > 20000), lowering
kernel.perf_event_max_sample_rate to 6250
[45310.627571] [drm:radeon_uvd_cs_msg] *ERROR* No more free UVD handles!
[45310.627575] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !
... and lots of such messages ...
[45323.651977] [drm:radeon_uvd_cs_msg] *ERROR* No more free UVD handles!
[45323.651979] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !


You see, that before doing FF there were some messages and long uptime without
any message. When I stop doing FF the messages stop.

The system is Debian GNU/Linux 8.0 Jesie

Do you run Kodi with the VA-API wrapper or the native VDPAU backend? The VA-API
wrapper isn't really supported any more, so the issue is most likely somewhere
there.

What happens here is that the hardware runs out of UVD handles because the
software stack is trying to play a lot of streams at the same time.
