<pre>I found the problem on my computer Toshipa S70
with VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06) was caused by commit
c6930992948adf0f8fc1f6ff1da51c5002a2cf95
file drivers/gpu/drm/i915/intel_dp.c
sequence around loop
for (clock = min_clock; clock <= max_clock; clock++) {
for (lane_count = min_lane_count; lane_count <= max_lane_count; lane_count <<=
1) {
Reversing this commit solved the problem, I recompiled the
the drim-intel-nightly (8734408c113bb38234ed03ec51c723b3deff579b)
and it works fine.
The error is reproducible, ie. by swithcing the sequence of the loops I can
reproduce the blury screen or flicker</pre>
