Hi Misc@,
is there anything on man (8) how to set irq allocation for certain
devices like NICs? I tried apropos but I can't find userland application
on base to change this.
Thanks,
In general allocating IRQs is a kernel thing and not something you
want to tweak.
What problem are you trying to solve?

sk0 shares the same irq as uhci, which is nothing attached to them. Our
plan is to disable/change setting for usb config from BIOS. But We really
need to gather more info on this. Any hints and suggestion will be
appreciated.
Thanks,
Insan
