dmesg with drm.debug=14
When playing back a video using VDPAU and UVD it first plays fine, but the X Server reproducibly hangs after a few minutes. Audio will continue to play, but no screen updates will happen any more, nor is there any reaction to keyboard input. I have to use Magic SysRq to switch to the console and kill the X server. From that point on no acceleration will work, and the video card fan gets audibly louder, until the system is rebooted.
When using Xv and no hardware decode acceleration, the video plays back fine.
This is using Linux kernel 4.1.1 and Mesa 10.3.7.
In dmesg, messages like
