I'm currently struggling with a hard hang on the Cobalt hardware which

I've got the rev 11 data sheet for the bridge, I was wondering if anyone
knows whether there is an errata sheet for this chip, and if so whether
anyone has a copy ?
I recall PCI device 31 on bus 0 was magic on all Galileo. Touching it
results in a system hang. Could that be what is hitting you?
Don't think so. Sometines, after a lot of bus master activity from the
Tulip NIC we get a Galileo interrupt (probably timer tick) and the first
time we touch a Galileo register in the interrupt handler the system
hangs hard :-(. It looks like some nasty interaction between the NIC and
the bridge.
