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?
