0 is 'On'. It will not do anything.

Do you physically have to remove the devices or can you simply remove the modules?

Noted. This is a common problem that we're trying to get to the bottom of.

Interesting. That backtrace and the cause (whether it's an actual Oops, a BUG() or a WARN_ON()) is important. Is there anyway you could hook up a serial console to capture the output?
Also, if you're willing, I would recommend trying 2.6.0-test5-mm2, which will allow you to try the original swsusp code (via /proc/acpi/sleep) independently of the more recent suspend-to-disk code (via /sys/power/state).
Thanks,
Pat
