If I have the io-apic enabled, I get no ACPI interrupts after resume.
The brightness and volume keys also stop working (these don't send ACPI
events, but seem to be on IRQ 9 anyway). The power button also generates
nothing. Booting with noapic results in everything working.
By the looks of it, the io-apic resume code rewrites all the registers
in the io-apic. Is it possible that state is getting lost in the
process?
