(yes, I know this is an old thread, but I just got my x40, so...)
I can replicate this behaviour on my IBM x40 (IBM partnr. US1H4BE,
machine-type-model 2386-H4G) with a snapshot from september 1st. I
tested with a LaCie external harddisk and a Plextor cd writer. Both
attach to uhub3 (ehci) before a suspend-to-disk (hibernate), and
to uhub1 (uhci) after resuming from hibernation.
