Correct on all counts. acpi=off changed how /proc/interrupts looked.

Plain rc3-bk2:

cat /proc/interrupts
           CPU0
  0:   24465969    IO-APIC-edge  timer
  1:       3894    IO-APIC-edge  i8042
  2:          0          XT-PIC  cascade
  8:          1    IO-APIC-edge  rtc
  9:          0   IO-APIC-level  acpi
 11:          0    IO-APIC-edge  ohci1394, radeon@PCI:1:0:0
 12:     208554    IO-APIC-edge  i8042
 14:     484633    IO-APIC-edge  ide0
 15:         24    IO-APIC-edge  ide1
 16:     100000   IO-APIC-level  CMI8738-MC6
 18:      96443   IO-APIC-level  eth1
 21:          0   IO-APIC-level  ehci_hcd, uhci_hcd, uhci_hcd, uhci_hcd

With acpi=off:

cat /proc/interrupts
           CPU0
  0:     411879    IO-APIC-edge  timer
  1:       1037    IO-APIC-edge  i8042
  2:          0          XT-PIC  cascade
  8:          1    IO-APIC-edge  rtc
 12:      15358    IO-APIC-edge  i8042
 14:      13668    IO-APIC-edge  ide0
 15:         24    IO-APIC-edge  ide1
 16:      21258   IO-APIC-level  ohci1394, CMI8738-MC6, radeon@PCI:1:0:0
 18:        404   IO-APIC-level  eth1
 21:          0   IO-APIC-level  ehci_hcd, uhci_hcd, uhci_hcd, uhci_hcd


And the patch worked.

With the patch:

cat /proc/interrupts
           CPU0
  0:     138277    IO-APIC-edge  timer
  1:        942    IO-APIC-edge  i8042
  2:          0          XT-PIC  cascade
  8:          1    IO-APIC-edge  rtc
  9:          0   IO-APIC-level  acpi
 12:        918    IO-APIC-edge  i8042
 14:      11189    IO-APIC-edge  ide0
 15:         24    IO-APIC-edge  ide1
 16:       7731   IO-APIC-level  ohci1394, CMI8738-MC6, radeon@PCI:1:0:0
 18:        177   IO-APIC-level  eth1
 21:          0   IO-APIC-level  ehci_hcd, uhci_hcd, uhci_hcd, uhci_hcd


Thanks for all your help. When should we see the patch in the kernel?
