nvidia0 em0 shared irq problem persists on dell precision 670
I synced sources today and tested the em changes, and the problem has
not gone away for me. nvidia0 and em0 are shown as shared with ioacpi
disabled using a device hint.
interrupt total rate
irq1: atkbd0 60 0
irq6: fdc0 10 0
irq14: ata0 16 0
irq15: ata1 47 0
irq16: nvidia0+++ 1267513 2162
irq18: uhci2+ 52688 89
irq23: ehci0 1 0
irq48: em0 106712 182
cpu0: timer 1167964 1993
cpu1: timer 1165966 1989
Total 3760977 6418
When disabling the ioapic, the rate falls to the 600s which is still a
tad high no?
I was running it with apic disabled as a work around, but I plan on
buying another processor for this box soon. Running it with a SMP kernel
with hyperthreading seems to allieviate some of the latency caused by
the high interrupt rate; however, I did have it hang once today.

nvidia0 em0 shared irq problem persists on dell precision 670
Is the firewire controller something that you can disable? Can you selectively disable some of the USB controllers?
