How current is your current? Mine is 6 days old, and a generic ofppc kernel
boots on my Pegasos2/G3 with 512MB.

It probably isn't important, but the recent revision is 1.11.
Did you boot the kernel from disk or over the net (100MBit or GBit-port?)?

A performance monitor exception!? How could that happen?
Unforunately ddb doesn't show the performance monitor registers. The
contents of MMCR0 would have been interesting.
The only location where the perfmon is used in the kernel is while
calculating the clock frequency. And this is during configure().
The G3/G4 manual says that MMCR0 "must be cleared at power up", which could
mean its contents is undefined, and with some bad luck we get an exception
as soon as we enable interrupts? But I cannot believe that...

Not really. The only difference between our systems is that you have a G4
and I have a G3.
It worked for you in the past?
Did you already test a kernel after the switch from pegasospci to gtpci?
Since the last months I get kernel panics when an USB device is plugged in.
I don't know if there was a modification in some USB code or whether it is
caused by a problem with gtpci:
