--- Comment #3 from Mika Kahola <mika.kahola at intel.com> ---
kms_cursor_legacy tests cursor behaviour in various cases such as flips before
and after cursor, two screen flips, modesets with blocking and non-blocking,
atomic and legacy scenarios and stress tests to mention a few.

The problem with the failing subtest occurs when we update cursor while doing
atomic display commits in non-blocking fashion. The failure can cause lockups
on screen as in this bug report or failure to update screen or cursor or both.

>From user perspective, it is a bad user experience if screen freezes for a long
time. Therefore, one could estimate the bug severity as high.
