Hi Humberto, Is the FIFO underrun reproduced? Is your result with the patch applied or not (comment 14)?

First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not. If bug investigation still in progress, please ignore this and I apologize! If you think this is not anymore valid, please comment to the bug that can be closed. If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug.
igt@kms_flip tests haven't show this warn since months ago. The kms_cursor_legacy assertions reported since comment 36 should be reported on bug 105493, if it's considered that it isn't the case, then open a new bug for CFL in specific. Thank you.
