(1) Deadlock
A few hours ago I wrote:

Now that I mentioned that inserting usb-storage hangs forever
and then causes a SCSI oops, the question arises how the hang
is caused. It turns out to be a semaphore deadlock.
What happens is that base/bus.c:bus_add_driver() downs
down_write(&bus->subsys.rwsem);
and then later usb/core/hub.c:usb_reset_device() downs
down_read(&gdev->bus->subsys.rwsem);
This is the same semaphore, and we have a deadlock.
