The IP27 PCI code as it is in CVS is incomplete or even broken - however fixing isn't entirely trivial. The current workaround which I use - and which due to being just an evil hack is not in CVS - to only scan the PCI code. The problem is the firmware does a very simple setup which hurts performance very badly, so eventually Linux will have to do a full PCI configuration for all PCI busses. > Now, the IOC3 makes a kernel panic.
