Sun 386i Panic: Wakeup while attempting to print to LaserWriter

[Chris Schanzle]

About one out of 15 times our Sun 386i (250 w/4.0.2) crashes with a Panic:
wakeup message when printing to the local (ttya) Apple LaserWriter.

It was suggested that I change the FLAGS field in the kernel config:

suntan:conf: diff SUNSET SUNSET~
217c217
< device      zs0 at obmem ? csr 0xFC000000 flags 0x2   irq  9 priority 6
---
> device      zs0 at obmem ? csr 0xFC000000 flags 0x3   irq  9 priority 6

But this hasn't helped.  Does anybody know what's the problem here?
