Followup to this: with 2.4.21-rc7-ac1, I get very different behavior. If I boot with noapic, my machine goes into an endless loop of
APIC error on CPU0: 40(40)
errors. If I boot regularly (APIC enabled), everything is fine. My machine has been up for almost a full day without a single lost interrupt message. This, BTW, is with ACPI enabled in both cases.
