I can successful netboot the 20000620-1.5 snapshot on a G4/400
machine - dmesg output below.

The Cylcades-8Y PCI card does get recognized, and after making the
/dev nodes manually (no support in MAKEDEV, send-pr to follow), I can
open a port on the card. The modem signals appear to be handled
correctly, ie. the attached modem lights DTR when the port is opened,
and kermit reports correct status of DCD and DSR. However, I cannot
send or receive any characters through the port. systat vmstat does
not list the irq (irq24) in the right column, which leads me to
believe that something is wrong with the interrupt management in the
driver.

Is someone using a PCI Cyclades-Y board on G3 or G4 Powermac with
NetBSD 1.4/5? If not, where should I start to look in the code to
trace the missing interrupts?
