- This indicates that the board has stopped reading in commands from the
- mailbox.. The last command (the one that timed out) was still
- unacknowledged in the mailbox. the board had not even read it in.
-
- I suspect a faulty board.. I have 3 running here

- why would the board post interrupts without having anything to report?

- I cannot get at the boards now to look at the version, but I have been running
- this drive now for nearly 2 years. NEVER with this sort of problem.
- some 20 or 30 busteks running under both 386bsd and MACH2.6.
- If there have been version changes over those 2 years, they have all worked.
