lspci -nn -s 06:00.0
06:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945A=
BG [Golan] Network Connection [8086:4222] (rev 02)

With the interface active and in use do:

sudo modprobe -r iwl3945

Approximately 2 seconds later the PC locks solid and requires a
power-off button restart.
