With the freeze patch installed and the power button patch in the kernel it can still fail to stay suspended. However I think there are two causes in my system and without them it will stay frozen at least until there is a power glitch:
- Bluetooth on, even with nothing paired, is certain to cause return from freeze
- Some things on USB can cause return from freeze (I had a USB hub and a card reader dongle and removed them both so I don't know which did it). Note that my Microsoft wireless mouse & keyboard (which has a tiny USB transceiver) does not cause any trouble.
