It's sorting by cpu usage, and look at my output:
top - 14:03:06 up 17:15, 1 user, load average: 3.12, 3.16, 3.35
Tasks: 98 total, 1 running, 95 sleeping, 0 stopped, 2 zombie
Cpu(s): 34.9% us, 65.1% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0%
si
Mem: 256876k total, 253764k used, 3112k free, 33732k buffers
Swap: 979924k total, 71668k used, 908256k free, 61896k cached

So it's using 34.9% from the user and 65% from the system. I understand
top not accounting for the 65% but why does it say 34% if my cpu load is
really around 7%? (adding up the non-zero entries of cpu usage)
Is there any other way to find out what's using the cpu?
My system started doing this when I upgraded to the 2.6 kernel. Usually
when I boot its fine, then after a while cpu usage goes to 100% and stays
there.. Once in a while it will go to normal again (sometimes after a few
days of uptime) then back to 100% usage.
It's really annoying.. Could this be a misbehaving driver? How would I
find out?
Thanks,
Leo
