With APIC at least it doesnt suprise me the least. The IRQ hack seems extremely racey. Remember on most systems (especially with PIII type APIC) IRQ delivery is asynchronous to the bus so you get
IRQ arrives sound card loop clean up IRQ IRQ sent still more work, do it done HANDLED
IRQ arrives sound card Umm duh no work for me NOT HANDLED
Whine
For anything where you get pairs of close IRQ's
