igt/kms_plane/plane-panning-bottom-right-suspend-pipe-C-plane-2

the cases above have the same issue.

QA blacklist 45 kms_plane cases because of this bug, any developer would help take a look at this bug?

Can you please retake the output of the testcase again? We've added a lot of useful logging to igt tests in the meantime.

Yeah we need to change this from timeout to fail to avoid getting blacklisted here ...

This has been changed in commit cff102e (lib: use test failure status for igt_set_timeout). Please re-test with this commit.

Test on the latest igt, the "timeout" goes away, it fails.
