Do you mean interrupt%? bsd.mp will probably drop that *way* down.
You may need to also disable USB (may have been one of the things fixed
by moving to either acpi or a newer bios, I don't recall).
Most of mine are on original bios, -current from around the time 4.1 was
tagged, with acpi on, USB off. They don't crash any more, but I have
recently noticed some odd problem with packet loss with the onboard
bge(4) though; if I ping *from* the h8ssl to another box there's no
trouble, if I ping from elsewhere to the h8ssl I get periods of a few
(1-10) minutes at a time with usually an hour or two between them
where there's 0.5 to 1% loss, a couple of RTM_LOSING, and sometimes
bad enough to cause bgp hold timers to expire on the ibgp sessions
to other h8ssl boxes.
The one of them with a quad em(4) is only affected by that to the
extent that all the ibgp peers are h8ssl with bge(4)...

the diff to if_em.c is 1000 lines. Some of it's PCIE support, but
there's plenty else.
here's dmesg from the one I have here (not a router, still sees packet
loss on bge though - this has the newer bios - as an aside, supermicro say
this has the erratum 89 fix in, I've yet to see an amd64 box which doesn't
trigger the warning though ...). Kernel is just generic with acpi enabled
and usb disabled.
