[mythtv-users] Often get GPU hang while running mythtv

[Scott Simpson]

I occasionally get a GPU hang when I run mythtv. I get this repeating in 
the system log:

Feb 06 16:04:20 mythtv kernel: i915 0000:00:02.0: [drm] GPU HANG: ecode 
6:1:80000f7b, in mythfrontend.re [2280]
Feb 06 16:04:20 mythtv kernel: i915 0000:00:02.0: [drm] Resetting chip 
for stopped heartbeat on rcs0
Feb 06 16:04:20 mythtv kernel: i915 0000:00:02.0: [drm] 
mythfrontend.re[2280] context reset due to GPU hang

I have this output from lspci:

Anyone seen such a thing? I have to reboot to reset it since my display 
hangs (although mythbackend is unaffected).
