Hi

I stumbled upon this old thread while debugging a hung cdrom_id task on
my Thinkpad X200.

Yes this seems to be a race condition or a deadlock while removing the
cdrom drive when undocking the notebock from the dock which contains the
cd drive. The process is already unkillable before any attempt to
suspend the machine.

Please see the requested dmesg output below. I can also provide
additional debugging information if needed.
