tm driver bug?

[Hans van Staveren]

We acquired a tape unit today, that is driven by an Emulex TM11 compatible
formatter ( or controller as we would say in the days of the PDP 11).
It seems to work OK, but I noticed one "minor" bug.

When given the command 'mt fsf 1' it is winding along happily for some
time and then it happens:
te0: lost interrupt
trap type 2, code = 0, pc = 80000d99
panic trap
  .
  .
  .
  .
DOWN he goes.

I had a quick look at the driver and noticed some funny timeout business.
That is probably the source of the trouble but before I spent time looking
at it, has any one noticed this before, or better yet fixed the bug?

All replies by mail will be gratefully accepted, especially those containing
a fix.
