panic: npxintr from nowhere

[bleader <bleader@xxxxxxxxxxxxx>]

Hi,

I'm trying to install DragonFly BSD onto a small geode based board
(http://www.pcengines.ch/alix2c3.htm if this can be of any use).

I'm booting up a laptop with the live CD, running the "Setup NetBoot
Install Services" to boot from PXE. Just to ensure this wasn't in a
given version I tried with:
- 2.2.1
- 2.4.1
- LATEST downloaded on 23th of november

Attached is the full dmesg, here are a few hilights:

npx0: <math processor> on motherboard
npx0: error reporting broken; using 387 emulator

npxintr: npxthread = 0, curthread = 0xc168c6f0, npx_exists = 0
panic: npxintr from nowhere
Trace beginning at frame 0xccc4ccf4

panic(c05acd1b,c05f199c,0,c168c6f0,0) at panic+0x8c
npx_intr(0) at npx_intr+0xd6

Debugger("panic")
