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 fault code = supervisor read, page not present instruction pointer = 0x8:0xc06b509e frame pointer = 0x10:0xde006a8c stack pointer = 0x10:0xde006a5c code segment = base 0x0, limit 0xfffff, type 0x1b, DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume IOPL=0 current process = 36 (swi1:net) trap number = 12 cpuid = 0 boot() called on cpu#0
