This bug is about flickering in BDW - this case is related to KBL based on
comment 48 - let's not mix these. kxra at riseup.net , please provide dmesg having
drm.debug=0x1e log_buf_len=1M used on kernel command line (see
https://01.org/linuxgraphics/documentation/how-report-bugs) into one of the
bugs given below query. Or if none of below bugs apply then please create new
one for KBL.
