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?
