<pre>So i completed the bisect run. I ignored the "new" start X results in black
screen issue (only X is affected, system doesn't freeze!, i was able to power
off the system via short press on the power putton) and continued with "bisect
good" whenever the KMS worked (= no screen corruption when KMS gets active) and
"bisect bad" whenever the KMS doesn't work (= heavy screen corruption when KMS
gets active). According to bisect this is the "root cause" commit.
0ffb0ff283cca16f72caf29c44496d83b0c291fb is the first bad commit
commit 0ffb0ff283cca16f72caf29c44496d83b0c291fb
