It's more likely that updating the system BIOS and trying to tweak any settings related to SMP or ACPI might help. You might also try enabling or toggling the "PnP OS installed", to avoid having the BIOS configure stuff it doesn't need to boot, and leaving FreeBSD to assign IRQs itself... If that doesn't help, I believe there's a freebsd-acpi list which contain people who can look at the dump of your BIOS and fix the broken IRQ assignments it is doing. -- -Chuck
