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.
