I guess it is possible that what I mistook for a hang was actually an incredibly
slow system, and that it would resume, eventually. I waited for 5 min and gave
up.

However, after resume was completed, system would hang on the *next* suspend to
ram.

Ingo, do you see this behaviour, or can you suspend/resume any number of times?
