Hello current's,
I have the ath driver running for a DWL-AG520 on FreeBSD 5.2.1, the card
seems fine for a short period of time, but then as data starts flowing the
machine hangs with a fatal trap 12.
The machine is a Dual Processor PIII on an Intel BX Chipset with 700MB RAM.
I think this may be SMP related as I found this whilst googling -
http://www.houseofcraig.net/README-0.2.0pre7.txt
Which mentions trouble with that card and SMP.
My Question is - is the problem SMP when using ath and if so how do I fix
this?? If not what the hell is it?
The exact error is:
fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x34002d85
