In servalan.mailinglist.fbsd-current you write: >I just upgraded to the latest sources (two hours ago) on my VAIO laptop and >I'm now getting dozens of messages: >Aug 22 15:00:07 sidhe /boot/kernel/kernel: usb0: interrupt, but not for us >Aug 22 15:00:51 sidhe last message repeated 8 times >Aug 22 15:03:02 sidhe last message repeated 19 times >Aug 22 15:12:59 sidhe last message repeated 92 times This is apparently due to a change last night in the uhci and ohci drivers to report interrupts the USB code sees but which don't correspond to any actual USB activity. I saw the same thing last night after I upgraded (to try out jhb's latest fixes, which worked like a charm on the sound problem). I note that on my system the uhci0 and fxp0 are on the same IRQ: uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0xef80-0xef9f irq 2 at device 7.2 on pci0 fxp0: <Intel Pro 10/100B/100+ Ethernet> port 0xef40-0xef5f mem 0xfea00000-0xfeafffff,0xfc4ff000-0xfc4fffff irq 2 at device 17.0 on pci0 I wonder if the "interrupts not for us" are actually interrupts from the Ethernet that the USB code sees because both the USB and the Ethernet are on the same irq.
