re: 5.99.30 sparc panic during startup

i don't see how without simply revert the change to convert to
using device_lookup_private().

the interrupt comes in and you have to look at all of the zs
devices on the system, because there is no information about
which channel interrupted (or even which zs chip!)

so you need some way to look up all of the softc's.

i am missing something obvious?
