From: Martin Peres <martin.peres at labri.fr> This patchset is mostly about fixing fdo bug #66177, reported by Dash Four. This bug is about fan/temp management not working after a suspend/resume cycle. Fan/therm management relies on ptimer's alarm feature to call periodically multiple callbacks that poll the temperature and update the fan speed if needed. The problem is that there is no easy way to make this work across suspend or hibernate cycles because it would require making sure the IRQs aren't serviced until all nouveau...
