Well I got hit rather fast and bad.
My FireWire connection is dead. The system recognises my camcorder and my external CD-writer without a problem, but the moment I start pumping data from one end of the cable to the other the system totally hiccups.
I even got a kernel panic - the first in at least 3 years of extensive OS X use.
When I don't move data via firewire I'm fine.
I am using a Sonnet Tango 2.0 (firewire and usb combo) on a B&W G3 (the onboard FW died shortly before christmas).
I will try to downdate to 10.4.3 somehow.
