--- Comment #13 from Maarten Lankhorst bugs@mblankhorst.nl --- Created attachment 164121 --> https://bugzilla.kernel.org/attachment.cgi?id=164121&action=edit Use exclusive wait to put the waiter at the end of the waitqueue
Ok seems I made a thinko. wait_event_interruptible_timeout and wait_event_timeout add items to the front of the queue instead of the back, this may result in fences never signalling.
Can you test the attached patch?
