I'm running this kernel now and the problem seems to have disappeared.
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?

Thanks,

Matthijs
