I was pretty confident that I told this happens upon modprobe -r
or rmmod (at least in the previous messages). The problem is not
(or at least shouldn't be) rmmod:
With a "healthy" disk nothing happens upon rmmod usb-storage even
if the disk is still plugged in (you can't mount the disk, that's
what happens). With this beast, even after scsi reports it offlined
=== [Edit:] even still after I unplug the disk =====
the disk, usb-uhci still tries messing with irqs; please see the
dmesg output.
