Driver Needed

[sls at allegra.UUCP]

I have been having the following problems with the Berkeley
4.1 tape driver, mt.c, which results in not being able to 
open the tape (TU78).             

After a Rewind:
mu0 hard error bn0 er=4034 ds=162200 (rdy,pres,onl,bot,avail)
mt: unit 0 random interrupt

At the next attempted use of the tape drive:
cannot open tape

Or, after loading a tape with a write ring:
mu0 hard error bn0 er=4034 ds=16400 (rdy,pres,onl,bot,avail)
mt: unit 0 random interrupt
mu0: no write ring

I have tried resetting the TU78 (by turning off the drive and hitting
the reset button) but this does not work.  The only solution so far has
been to reboot. 

Does anyone have the fixes for these bugs?    
If so, please send mail to:
