It also happens under some circumstances in the normal -current branch :-( [ discussion about problems wrt. SMP-kernel with option APIC_IO not booting deleted ] > Is there anything in the BIOS that looks like it might affect this behavior? Yes. The MPS 1.4 enable switch in the BIOS was disabled. Enabling it helped, and I'm currently running the SMP kernel with option APIC_IO as I write this. As expected, not having APIC_LAZY defined immediately caused lost interrupts when a new interrupt arrives before the interrupt is reenabled. - Tor Egge
