--- Comment #3 from Swati Sharma <swati2.sharma at intel.com> ---
Based on bug history issue is seen only 5% times on KBL platform whereas seen
95% times on shard-skl. On KBL, reproduction rate is quite low - issue occurred
5 times almost 3 months back whereas on shard-skl issue is seen recently
(almost a week back). May be we can drop, KBL from the affected platforms.

IGT has 100% failure rate. IGT is getting failed because of CRC mismatch issue.
Issue is happening for the following subtests:

igt at kms_frontbuffer_tracking@fbcpsr-rgb101010-draw-mmap-cpu

igt at kms_frontbuffer_tracking@fbc-rgb101010-draw-blt
igt at kms_frontbuffer_tracking@fbc-rgb101010-draw-pwrite

The real subtest to be executed depends on whether the pixel format(rgb101010)
is supported by the features being tested or not. Need to check which subtest
is actually failing (draw_subtest(t) or badformat_subtest(t)).

In last 15 runs
https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html?testfilter=@fbcpsr-rgb101010-,
issue is not seen.
