That's great, thanks. Can't believe I overlooked that!
I'm also on irq 16, it seems, and only sharing with one usb port:
atte at vestbjerg:~$ cat /proc/interrupts | grep ohci1394
16: 110664 111091 IO-APIC-fasteoi uhci_hcd:usb3, ohci1394
1) Why doesn't `pidof IRQ-16` return anything here, I guess I need that
to call chrt, right:
atte at vestbjerg:~$ pidof IRQ-16
atte at vestbjerg:~$ pidof IRQ 16
atte at vestbjerg:~$ pidof "IRQ 16"
atte at vestbjerg:~$ pidof "IRQ-16"
atte at vestbjerg:~$
2) I'm hoping the usb shared with my firewire is one of the three usb
ports, how can I investigate further in this direction? Ultimately I'd
like to be able to leave whatever-usb-is-sharing-irq-with-the-firewire
