[comp.unix.microport] YAMB: cartridge tape rewind freezes system.

steve@nuchat.UUCP (Steve Nuchia) (04/10/88)

I've got the everex tape drive kit, with the driver supplied through
microport.  Seems to work ok, except for one thing.

Rewind freezes process dispatch.  I'm not even sure how that
might happen, unless the driver is busy-waiting.  Interrupt
driven things still happen - keyboard echo, virtual console
switching, but no process gets any cpu (apparently) until
the rewind completes.  Then all procedes as if nothing had
happened.  Except for the uucp connections and dial-in users
that have given up by that time :-(

thought y'all might like to know.
