What you have is a controller hang. You can't kill the process because
it is waiting for a controller event and the software signal can't
touch the process until that event happens.

If you know how to reset the controller, you can twiddle bits by
adb'ing /dev/kmem. Sometimes a power cycle of the tape controller will
work, but I won't guarantee that won't crash your system.  Otherwise
the only other recourse is to power cycle and reboot.
