Subject: top displaying 50% si time and 50% idle on idle machine

Hi,

Kernel 2.6.17.11 with tg3 network driver, NAPI enabled (Distro CentOS 4.4).
top shows strangely 50% idle even if the machine is _completely_ idle.

top - 01:04:30 up 4 days, 12:05, 2 users, load average: 0.00, 0.00, 0.00
Tasks: 34 total, 2 running, 32 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0% us, 0.0% sy, 0.0% ni, 50.0% id, 0.0% wa, 0.0% hi, 50.0% si
Mem: 3634452k total, 313284k used, 3321168k free, 71308k buffers
Swap: 505896k total, 0k used, 505896k free, 220272k cached

I find this pretty alarming - can somebody please enlighten me?
Please include me on CC.
Thanks,
