[Qemu-devel] [PATCH] PIC spurious interrupts

[Hampa Hug]

Hello

This patch fixes two issues:

- Spurious interrupts do not occur in practice.
- If an unexpected spurious interrupt in the slave PIC is
  not acknowledged by the interrupt handler, no EOI will
  be sent to the master PIC (for IRQ 2), leaving all
  interrupts of lower priority disabled (unless SFN mode
  is used).

This patch fixes the OS/2 boot lock-up problem for me.

cheers
Hampa
