great. I've applied these changes and have released the -28 patch. (note that the last chunk of your patch was malformed, have applied it by hand.)
i'm wondering what your thoughts are about IOAPIC_POSTFLUSH - i had to turn it on unconditionally again, to get rid of spurious interrupts and outright interrupt storms (and resulting lockups) on some systems. IOAPIC_POSTFLUSH is now causing much of the IO-APIC related IRQ handling overhead.
