[Intel-gfx] [drm:gen8_de_irq_handler [i915]] *ERROR* Fault errors on pipe B: 0x00000080

[Peter Zijlstra]

Hi All,

My desktop (Intel(R) Xeon(R) CPU E3-1245 v5 @ 3.50GHz) is spewing tons
and tons of:

[  778.461227] [drm:gen8_de_irq_handler [i915]] *ERROR* Fault errors on pipe B: 0x00000080
[  778.477763] [drm:gen8_de_irq_handler [i915]] *ERROR* Fault errors on pipe B: 0x00000080
[  778.577718] [drm:gen8_de_irq_handler [i915]] *ERROR* Fault errors on pipe B: 0x00000080
[  778.577824] [drm:gen8_de_irq_handler [i915]] *ERROR* Fault errors on pipe B: 0x00000080

at a rate of ~3 per second, and X isn't as stable as one would like (it
crashes every few days, sometimes taking the whole kernel along). Sadly,
this being my desktop, I don't actually have a serial line connected to
it, although I could hook one up if required.

It is currently running 5.6.14-1 (as per debian testing), but it seems
to have done this for a while, I only now got around to reporting it :/

What else I you need to know, want me to try etc.. ?
