I think that the same issue is present also on the non pae kernel.
Seen on an EEEPC 1000H with an atom cpu and the 32 bit ubuntu natty.
Since at the same time I upgraded the kernel I also upgraded the intel drivers, I need to double check that it is not the latter being guilty for the suspend failure. However, I expect that this is a kernel regression.
On this machine:
2.6.38-8 failed resume from hibernation
2.6.38-9 from the proposed repo could both hibernate and suspend properly
2.6.38-10 cannot suspend (suspend is started, but the machine does not power down, hangs on, with the leds indicating bluetooth/wifi status still on).
