Why the kernel panic?

[Sostris]

I posted this in the Wireless forum, but didn't get a response. It seems that some people are using miniPCI cards based on the Atheros 5212 chipset successfully. But when I install a Wistron CM9 card in an Alix box running nanobsd 1.2.3, I get a KP:

What's the BIOS on the Alix? Are any settings non-default? I've run a generic Atheros card (have to check, but I think it's 5212 based) in a 2D3 with 99h running a 1.2.3RC3 nano snap.

@dotdash:

From the console output:

Geode LX: PC Engines ALIX.2 v0.99h tinyBIOS V1.4a (C)1997-2007

I haven't changed any settings.
