List,Every time I browse my 'journactl -b' logs I always see the following error:[drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A[drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrunIt also happens around times when I'm doing something graphically intensive and often precedes lockups. But these lockups are rare and do not happen often. The error message itself appears on nearly all of the Intel HD graphics chips I've used which are both the Intel HD 4000 and Intel HD 4600.I'm just curious as to any workarounds that could solve this in the short-term. Of all the bug reports I've read they always end with no resolution or "version 4.0 of the Kernel will solve this", but I'm on Kernel 4.1+ and it's still not solved yet.Thank you for any information you can provide...
Downgrade from 4.1 to 4.0 to fix it.
