Might be the same as bug #91452, but in my case the crash does not occur randomly but reliably after at most 10min. dmesg: [ 764.492100] [drm] stuck on render ring [ 764.493303] [drm] GPU HANG: ecode 8:0:0x85dffffb, in X [2336], reason: Ring hung, action: reset [ 764.493307] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

*** This bug has been marked as a duplicate of bug 89360 ***
I am not convinced that this is a duplicate of bug 89360. The description of bug 89360 says that the system freezes totally. This is *not* the case here. The X server does recover, continuous to run but disables acceleration afterwards.
