I've done a dozen or so undocks and suspends, without any problems. Also, the "udisks-daemon" process in ps now says "not polling any devices" after undocking, where it would continue to say "polling sr0" before. I'll continue running this kernel for a while and inform you if the problem resurfaces. Any other tests I should be doing?
