concluded that most of the time the

Beware...their patch does a malloc M_WAITOK in interrupt state. I've
pointed this out to them, but they haven't changed it yet.

With 1800 interfaces in the system Freebsd seems to use about 50Mhz of cpu
when idle in "interrupts" even when there are no interrupts to process. on
a 500Mhz box it uses 10% of the cpu and it seems linear with different
speed processors.
the 1800 interfaces are 900 DLCIs on a T3 frame with 900 b
