It should match up > with the usbX number in the above list. Given that I get : tmp199:~ # lsusb ... Bus 007 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port tmp199:~ # cat /proc/interrupts CPU0 CPU1 ... 19: 996143 995511 IO-APIC-fasteoi ata_piix, ata_piix, uhci_hcd:usb5, uhci_hcd:usb7 tmp199:~ # my USB GPS receiver and my sata disk still share the same interrupt, I assume ? What's changed now is that this interrupt line is now IO-APIC-fasteoi instead of XT-PIC-XT-PIC. Maybe there's something to look at there ? > > Glad enabling APIC in your BIOS fixed this.
