The old kernel did not report interrupts...

Ian Dall has problems connecting his sun3 to his pc532 with the new
driver. I just tested it between two pc532s running ppp with 57600
baud (and hardware handshake). I never get fifo overruns. When doing
tests with ftp, I get about 5400 bytes/second. The console port of my
second pc532 is connected to tty01 on my main machine. When I connect
to the second pc532's console (without handshake) I get fifo overruns
from time to time (not often).

BTW, I just checked in a new method to handle software interrupts. It
works fine on my machine, but I'd be glad if there where some testers
out there. The new method is based on a idea from Phil Budne. I'm using
a spare interrupt in the ICU to trigger a call to check_sir. The interrupt
I'm using is the same as Phil is using in the scn driver when the HSOFT
option is present. If you have HSOFT in your config file, this will no
longer work.
