I've seen this problem on a NetFinity 5000 with 1.6_BETA3. 

I thought Jason's commit in rev 1.10 of sys/dev/pci/if_pcn.c had
fixed this (which I pulled up to -1-6 as rev, but obviously

Try booting the machine on 1.6_RC1 without the cable plugged in, and
then plugging the cable in after boot.  It is still likely to fail,
but it may not panic immediately.
