Hi,
Yes, I think I'll go the initrd route. However, hammering on the machine last night reproduced the malfunction regardless of whether the microcode was loaded or not!
(Addressing list in general:)
This board (Supermicro PIIIDME, i840 chipset) has been stable for almost 3 years, since between 2.4.0-pre6 and 2.4.0-pre9 IIRC. All recent hangs and lock-ups have been attributable to the IO subsystem in 2.4.20, and it just ran 2.4.21 for 3 solid weeks. The only thing that has really changed recently is the weather, but the lm_sensors package (2.6.5) reports that everything is fine.
Booting with "acpi=off" has so far prevented the kernel from hanging just after the "Freeing unused kernel memory" message. However, the kernel still hung later: the first time was when reading lm_sensors after one CPU had reached the magic BIOS setting of 55 degrees C under high load. This hang took out the keyboard, mouse and serial console straight away, but left the ethernet interface running for a few minutes. The second hang was more spontaneous, and killed the box outright.
Do ATX power supplies have temperature sensors built into them? I have just upgraded my PSU from 300W to a brand new 400W one, so doubt that it's faulty. Could the power supply be triggering a temperature-related ACPI event? I seem to recall the boot-log mentioning assorted S and C events being supported. (Can't remember which ones exactly: S0 and S3?)
And I have already run memtest for 2 hours without problems.
Cheers, Chris
