Boot withg the "noapic" option. Quite how your system has managed to
lose an interrupt in the APIC hardware I don't know, but the APIC's
certainly have bugs. It could also be an edge/level trigger but if the BIOS
confused it because IRQ15 was for some kind of IDE device, but I see no
evidence of that.

If it happens with APIC disabled ("noapic")  then the second option might
be worth investigating.
