I've just installed 5.2-CURRENT (post -BETA branching) to my Asus P2B-DS 
based system, and I am seeing slow performance. Looking at the output 
of "ps -axu" I can see massive amounts of Interrupt activity (removed 
VSZ and RSS fields to save space):

USER    PID %CPU %MEM   TT  STAT STARTED      TIME COMMAND
root     30 95.3  0.0   ??  RL    1:08PM   4:11.77  (irq20: acpi0)
root     12 53.9  0.0   ??  RL    1:08PM   5:08.86  (idle: cpu0)
root     11 50.0  0.0   ??  RL    1:08PM   4:28.89  (idle: cpu1)

# uname -a
FreeBSD nobby.int.athame.co.uk 5.2-CURRENT FreeBSD 5.2-CURRENT #2: Mon 
Dec  8 21:32:07 EET 2003     root at nobby.int.athame.co.uk:/usr/obj/usr/
src/sys/NOBBY  i386

This happens both before and after installing the 20031203 patchset. 

The box was previously running 5.1R with no apparent problems.

From dmesg:
acpi0: Overriding SCI Interrupt from IRQ 9 to IRQ 20


I've read through as much of the -current archives as possible, but I 
can't see anything that helps me diagnose the problem.
