kernel BUG at drivers/usb/storage/usb.c:848

Hello,
Running Kernel 2.6.4-mm2 (We use an mm2 kernel because of problems with
highmem and cryto-loop playing together which seemed to be solved in
mm2) and dd'ing from a IDE disk in an external USB case, the following
just happened (from /var/log/syslog):

The symptoms are that "ps aux" shows all processes trying to access the
disk (including the dd command) in D+ state, and the kernel does not
recognize that I removed and re-plugged USB devices in this slot. (I did
not test unplugging the other of the two USB slots I have because that's
my mouse :-)
Is this a known issue that is solved in later kernels?
Thanks,
Markus
