Hi, I'm running freebsd 7.0-RELEASE-p4 on a 4-core amd64 box. nearly 100% of 1 cpu is constantly being used handling irq19: uhci4 interrupts. This seems to happen both with and without any USB devices plugged in:
vmstat -i interrupt total rate irq1: atkbd0 5 0 irq6: fdc0 1 0 irq17: mskc0 dc0 1180547 18 irq18: skc0 uhci2* 163250699 2512 irq19: uhci4++ 3187989508 49072 irq23: uhci3 ehci1 31 0 cpu0: timer 129208570 1988 cpu1: timer 129208457 1988 cpu2: timer 125750147 1935 cpu3: timer 125750122 1935 Total 3862338087 59452 dmesg uhci4: <UHCI (generic) USB controller> port 0xa400-0xa41f irq 19 at device 29.1 on pci0 uhci4: [GIANT-LOCKED] uhci4: [ITHREAD] Any idea what's going on here and/or how to fix this?
