Missed clock interrupts...



Ok.
First success in trying to figure out where the system might be spending unreasonable amounts of time.

Just thought I'd send this in, in case someone have any good ideas before I continue digging...

db> bt
panic: Missed clock interrupt!

Stack traceback :
0x86afed1c: bqtbug+0x40(0x18,0)
0x86afed6c: mi_switch+0x146(0x81ab92e0)

bqtbug() is my small catch function that triggers a panic in case the system now is lowering spl to allow for a clock interrupt, and the clock hardware indicates that a clock interrupt have been missed.
