In the hours since applying the new mammoth Security Update, I've had
about seven kernel panics. They seem to be caused by copying any file(s)
from any partition of my Firewire400 drive to any other partition.

The crash reporter lists the same cause though:
panic(cpu 0): BlockAllocateContig: allocation overflow on "Taliesin"

Anyone else having problems, or am I playing the Blame-The-Update game
by myself this round? :)
