AFAICT this is harmless. I get several such messages in kern.log per day:
kernel: error: [drm:pid-1:intel_pipe_update_start] *ERROR* Potential atomic
update failure on pipe A
Sometimes I get this:
kernel: error: [drm:pid-1:intel_pipe_update_end] *ERROR* Atomic update failure
on pipe A (start=252802 end=252803)
And rarely this one:
kernel: error: [drm:pid-1:intel_cpu_fifo_underrun_irq_handler] *ERROR* CPU pipe
A FIFO underrun
All this with no visible impact on X session, so I guess that i915 driver is
able to recover from it.
