John, thanks for bringing it this far. Can someone verify the IRQ line is remains asserted? If the IRQ line is asserted, this sounds like a problem in iosapic code. I've seen this behavior before when iosapic_isr() didn't write the correct value to the EOI register. I'll review the iosapic code. But if someone could give me confidence the IRQ is asserted, I'd appreciate it. thanks, grant Grant Grundler Unix Development Lab +1.408.447.7253
