>Description:
On FS AMilo Pro V3515 I'm getting fatal page fault after cvs update on 
13/11/09. Kernel build went fine, but when booting the new kernel it spits 
error and drops to ddb:

db{0}>trace

uvm_fault (0xc0b69240, 0, 1) -> 0xe
fatal page fault in supervisor mode

Faulted in DDB; continuing

dmesg in ddm showing (sorry, a few lines shown only as I don't have other means 
to get the full dmesg):

Could it be an ath0 related problem? It is not functional, I've submitted the 
PR earlier this year:

This is the last working dmesg (from May):

Before updating src with cvs I've tried the snapshot and it failed also. I 
think the problem started before this update, but I haven't updated this 
machine in a while, and I do remember some problem with booting a few months 
ago. I also tried to update from source on 15/11/09 but the error is still 
there, preventing the boot.

Pls let me know if I could provide some more output.

Thanks
>How-To-Repeat:
Get recent source and try booting the new kernel on FS Amilo Pro.
