Ok, for the record, here's what I tried. I have rebooted between tests
to make sure there's no state pulled in from the previous test:
2.6.36-rc7, no changes, pm_async 1 : suspend fails
2.6.36-rc7, no changes, pm_async 0 : suspend fails
2.6.36-rc7, 152e1d reverted, pm_async 1 : suspend works
2.6.36-rc7, 152e1d reverted, pm_async 0 : suspend fails
2.6.34.7, no changes, pm_async 1 : suspend works
2.6.34.7, no changes, pm_async 0 : suspend works
I am not sure how this should be interpreted.
