Hi, I am using kernel 5.3.4 with those boot options (with no success - still
happening):

intel_idle.max_cstate=4 i915.enable_psr=0

but still occasionally I get:

[15807.397665] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe B FIFO underrun

and my external attached display port monitor on the dock is going black (only
the left one, the right one stays ok) and about 1-2 seconds l8r picture is
there again.

Anything else I can provide or try to get rid of those flicker / black screen?
