--- Comment #2 from Daniel Vetter <daniel at ffwll.ch> ---
The calltrace doesn't look specific to kms_cursor_crc, I think this is just due
to modesets in general.

Can you please figure out how else to reproduce this with some other testcase
or sequence of operations and then attempt a bisect? Unfortunately we can't
bisect with kms_cursor_crc easily ... Note that Paulo's pm_pc8 has tons of
special-purpose testcases for runtime PM - and the backtraces are all in
runtime PM code.

If you can't find a different way to reproduce this backtrace I'll explain how
to work around the now resolved issue with kms_cursor_crc and still be able to
bisect.
