Despite the fact that this wasn't documented in the BIOS update, an update for my board (MS-7030 Neo Platinum by MSI) supposedly fixing "Fan Function" actually corrects the IO-APIC and NMI bugs. I now get the following in dmesg instead: Calibrating delay loop... 3973.12 BogoMIPS (lpj=1986560) Mount-cache hash table entries: 256 CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line) CPU: L2 Cache: 512K (64 bytes/line) CPU: AMD Athlon(tm) 64 Processor 3000+ stepping 00 Using local APIC timer interrupts. Detected 12.561 MHz APIC timer. testing NMI watchdog ... OK. So I'm a happy man. Whether this is at all related to the problems I was having before, I don't really know. If the problem doesn't reoccur, I could very well have wasted your time. -- Cheers, Alistair. personal: alistair()devzero!co!uk university: s0348365()sms!ed!ac!uk student: CS/CSim Undergraduate contact: 1F2 55 South Clerk Street, Edinburgh.
