>Description:

A 1.6BETA system panics with

Kernel page fault, code 0
Stopped at fr_checkicmp6matchingstate+0x229      movzwl  0x2(%eax)

A kernel trace shows:

This is the third time the machine paniced exactly at the same place,
always with similar kernel traces. The first time this happened
the machine was running 1.6BETA1.
