Extremely high interrupt count / load on recent CURRENT

Hi everyone,
Since my last csup, I'm encountering very high interrupt counts (and
thus, a high associated interrupt load) on my workstation.
vmstat -i reports:
interrupt total rate
irq1: atkbd0 26087 1
irq14: ata0 58 0
irq16: emu10kx0 1051388503 78968
irq17: nvidia0+ 1189799 89
irq20: ohci0 16596 1
irq21: ehci0 1 0
irq22: atapci1 1387849 104
irq23: atapci2 905538 68
irq24: arcmsr0 176404 13
irq27: isp0 85 0
irq28: bge0 37642180 2827
cpu0: timer 26627670 1999
cpu1: timer 26595670 1997
Total 1145956440 86071
The problem is, when I remove the snd_emu10kx driver (I load it as a
module in loader(8)), then irq28: bge0 starts to exhibit the same
pattern, generating thousands of interrupts.
My kernel is GENERIC + ULE - WITNESS, but the problem also
occured using plain GENERIC. dmesg is available at
http://rink.nu/tmp/dmesg-pitchfork.txt
Can anyone help me track this down?
Regards,
