Sounds very much like the problem I have with 2.6.34 final. Did not happen with 2.6.34-rc7 which suspended just fine, but happens quite regularly on 2.6.34 final - not every suspend but each 2nd or 3rd attempt. I stopped doing suspend-to-ram due to this, because it's unreliable. Suspend-to-disk works just fine. >> Is this a known problem? > > No, it's not. > >> I had rock stable suspend with 2.3.33.x.
