This is a dual processor box, but I gave up and took SMP and APIC out of the kernel back in mid-April because the system would always panic on startup if I had both multiprocessor support and a RAID array defined at the same time. I made a thread about it on freebsd-questions but got no responses, so in complete bafflement I just turned off the multiprocessor support and rebuilt everything. The RAID was more important to me. http://docs.FreeBSD.org/cgi/mid.cgi?Pine.NEB.4.58.0404292248590.14141 I wouldn't be a bit surprised if that's a hardware problem. This old motherboard has a lot of quirks and I think it's probably going to die the next time I open the case. Thanks for the tip though. I wouldn't have thought of that.Received on Tue Jun 01 2004 - 17:46:18 UTC
