Well, FWIW, I have the same sort of machine (same motherboard and
processors), but running with -current from early December. I haven't
had any trouble.
I've got SCSI disks, though, not IDE. I do have two DEC Tulip based SMC
cards, though.
One question I have, though, is what kind of RAM you have in the machine?
i.e., what configuration. I tried putting 256MB in my machine, using 8
32MB (parity) SIMMs, but I wasn't able to keep it like that. I got random
NMIs with 8 SIMMs on board. I reduced it to 6 SIMMs (192MB), and the NMIs
stopped.
I'm fairly certain they weren't parity errors, since I've had bad memory on
other machines and FreeBSD would actually panic with a "ram parity error"
NMI. The NMI panic message I got with these errors didn't state a specific
problem.
The SIMMs I have all have 24 chips on board, so they're within ASUS' stated
specs, but my guess is that I exceeded the load that the memory subsystem
could take. The NMIs generally only occurred under high memory load.
It certainly sounds suspicious that these machines fail under SMP with
both Linux and FreeBSD.
In case it helps, I've attached the output of mptable -verbose -dmesg from
my machine.
