Anyone notice anything strange here? Why ohci (usb) got so huge number of=20 interrupts? Even if I have no usb devices connected to this box. 39.6%Sys =A037.9%Intr =A00.0%User =A00.0%Nice 22.5%Idle=20 # systat -vm Interrupts 101k total 96514 ohci0 ohci ata0 irq14 587 twa0 irq16 em1 irq25 2000 cpu0: time 2000 cpu1: time =46reeBSD 7.0-STABLE-200803 #0: Mon Mar 10 18:53:59 UTC 2008 That irq problem was detected originally with ps/2 keyboard without any usb= =20 device attached (dmesg info here is taken later).
