It isn't (*exactly*).

It is a problem. The DELUA takes a LONG time to run its self-check.
On Unibus reset it runs its self-check. So there are two ways to get it up:
1) Fix the probe routine to wait until the device is back from self
test (or at least DELAY a long time so you're sure it's done with
the self check) before trying to get it to interrupt.
2) Boot the kernel by (on a 780)
and by the time you can type in the name of your kernel
and hit return the DELUA's self check will be done.
Of course this isn't convient in a long term, but you can
at least get the machine up to go in and fix the source.
