Can anyone help me diagnose this please? I'm on 10.0-RELEASE on a Thinkpad
X200s. In top I see around 30% CPU listed as 'interrupt' even when I'm only
running Xorg (with Xfce as the window manager) with no other applications
open:
last pid: 1946; load averages: 1.09, 1.30, 1.24
up 0+00:59:59 21:56:20
54 processes: 1 running, 53 sleeping
CPU: 0.4% user, 0.0% nice, 0.2% system, 32.8% interrupt, 66.6% idle
Mem: 188M Active, 282M Inact, 283M Wired, 22M Cache, 206M Buf, 1127M Free
Swap: 4096M Total, 4096M Free

How do I diagnose what's using my processor?
Thanks in advance.
