This is _by far_ the most common backtrace for i915 on retrace.fp.o, and
|
|
|
9a25d0e |
it's mostly useless noise. There's not enough context when it's generated
|
|
|
9a25d0e |
to know if something actually went wrong. Downgrade the message to
|
|
|
9a25d0e |
KMS debugging so we can still get it if we want it.
