Hi Nikula,

All logs are around 5GB. So, I only uploaded log12&13 (attached file in
comment#11).

I always can get following kernel message in fail cases
$ grep -r -e "got hpd" .
./08_fail/kern.log:kernel:[ 621.812487][drm:intel_dp_hpd_pulse [i915]] got hpd
irq on port A - short
./06_fail/kern.log:kernel:[2428.068094][drm:intel_dp_hpd_pulse [i915]] got hpd
irq on port A - short
./12_fail/kern.log:kernel:[1318.258726][drm:intel_dp_hpd_pulse [i915]] got hpd
irq on port A - short
./10_fail/kern.log:kernel:[ 723.448265][drm:intel_dp_hpd_pulse [i915]] got hpd
irq on port A - short
