"God does not play dice" said Einstein, but the assignment of IRQ's at boot surely seems to be a bit of a random game (which only proves that Linus isn't God, I suppose ...) I would like to automagically increase the priority of the IRQ associated with my soundcard - peek at "the dice" before placing my bet so to say - how do I do that? I used to have: chrt -f -p 80 `pidof IRQ-20` .. in rc.local, but sometimes the relevant IRQ changes to 19 (giving IRQ-20 to something else), which may or may not cause a hanging system. from (todays) /proc/interrupts: [...] 19: 49 0 IO-APIC-fasteoi ehci_hcd:usb1, uhci_hcd:usb2 20: 8416716 0 IO-APIC-fasteoi firewire_ohci, HDA Intel, uhci_hcd:usb5
