One last followup (and I have moved it to freebsd-smp as it really looks
like an smp problem). Rebooting with my UP kernel causes things to
return to normal. My interrupts hover in the ~300/sec range and tty out
char/sec are virtually zero unless I start doing something.
Note that this is on an ASUS XG-DLS motherboard with dual Xeon
400MHz/512KB cache CPUs.
I have included the dmesg output for both the UP and MP kernel
boots.
