Yes, I had capacitor problems too. It drove me crazy trying to work out what was going on until I read about the Capacitor Problem (http://www.dashdist.com/1u2u/company/capacitor.html). I replaced them all, and it has been perfectly stable ever since. Well, under Linux anyway (and NetBSD on one CPU).

Ah, now this is interesting. I did not realise that there was problems running a non-ACPI kernel on an ACPI system.
Thanks for the info guys, I will build GENERIC.MPACPI and see how it goes.
