Confirmed -- and I can hopefully shed some light on this as well.
Seems that this (acx wireless) is the common thread/culprit: acx_l_process_authen+0x124/0x380
Background:
I had an RT2500 wireless card on WEP that used to work on 8.04 but doesn't even link on 8.10 (separate problem) and so I replaced the RT2500 with this Netgear WG311 (Texas Instruments) based card. It gives a kernel panic and doesn't even survive boot. I plugged in a null modem, which allowed me to spot the culprit, and a google led me here.
