Just in case nobody gives you a suggestion based on more understanding
than I have, here's a possible thing to try:  Remove the scsi and tape
modules and then reinstall them.  For example, if your scsi module were
aic7xxx and the tape module is st (you should see the modules when you 
type "lsmod"),

rmmod st aic7xxx; insmod aic7xxx; insmod st

might do enough resetting to let the process free itself, perhaps without
crashing your machine.
