FreeBSD azimov.videotron.ca 3.0-980521-SNAP FreeBSD 3.0-980521-SNAP #0: Sun May 24 14:12:46 EDT 1998 rubik@azimov.videotron.ca:/usr/local/src/sys/compile/AZIMOV i386
>Description:
The driver uses a wrong index variable to store the value of the MAC
address that was read from the card. The value read is written to a
semi-random place in the kernel causing the system to crash a few
seconds after booting.
>How-To-Repeat:
Boot a current kernel with a 3COM EtherLink III PCMCIA card inserted.
