I'm running FreeBSD 7.1 on a new Dell Inspiron 530s. I'm having an issue where the same IRQ is being assigned for multiple devices, and I have a device that absolutely needs its own IRQ. The BIOS is very limiting, and won't allow me to disable shared IRQ assignment. Some suggestions I've read about booting FreeBSD with ACPI hasn't been an option, because without it enabled, FreeBSD does not see the SATA controllers/disks, and thus won't boot. Linux has a utility called irqbalance (http://www.irqbalance.org/) that seems like it could be promising, but of course it is Linux-specific. Is there any way in FreeBSD that I can help the system decide which IRQs to assign to what?
