Yes I think that I am experiencing quite the same problems.
I have an external usb cd recorder. I attached it and tried to blank a
disk but cdrecord stopped and sent an error message. I disconnected the
device and tried again but I got error messages from cdrecord and from
the system (scsi subsystem?). I disconnected the device again and
reconnected it but the device does not "appear" and, moreover, "ps aux"
"top" are stuck waiting for something (?). Hitting ^C does not help for
the moment.

Is anyone seeing deadlocks with USB devices on 8 RELEASE? This is a
definite regression from 7.1 and 7.2 for me. I had just upgraded my
laptop an HP NX6125, AMD Turion 64, ATI Xpress 200M Chipset.
Anytime I insert or remove a USB device, WIFI chipset (broadcom with
ndis driver)/Bluetooth, External USB hard drive, The system becomes
completely unresponsive. If you look at the top output below my
attempt to run a zpool import on the Western digital hard drive I have
has stopped in tx->tx and I can't kill the process.
