*** Bug 97976 has been marked as a duplicate of this bug. *** Created attachment 126871 [details] [review] possible fix Does the attached patch fix the problem for you? With the patch, when playing problematic videos, I get a black screen instead of a partial display with green artifacts. Also, with and without the patch, dmesg catches the following when playing the problematic videos (I should have had a look previously): [76261.125581] [drm:radeon_uvd_cs_parse [radeon]] *ERROR* Handle 0x8fd80001 already in use! [76261.125594] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream ! [76261.126059] [drm:radeon_uvd_cs_parse [radeon]] *ERROR* Handle 0x8fd80001 already in use!

[76261.126452] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream ! Should be fixed in Mesa master as of commit 13cb41f666212ed50a7939a37a373b4431a84033. Please re-open if the problem persists. (In reply to Nicolai Hähnle from comment #4) > Should be fixed in Mesa master as of commit > 13cb41f666212ed50a7939a37a373b4431a84033.

And I still get the following error: [...] [ 286.174162] [drm:radeon_uvd_cs_parse [radeon]] *ERROR* invalid reloc offset 13FA000!

[ 286.270257] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream ! I confirm a bug. It occurs when playing h264 encoded videos using hardware vdpau acceleration.
