Hello

I've searched the internet but I couldn't find the answer.
KDE's system guard shows that something is using almost 100% of CPU, but it doesn't want to tell me who.
If I run top I get this:

top - 16:13:13 up 4:13, 1 user, load average: 1.27, 1.57, 1.63
Tasks: 109 total, 1 running, 108 sleeping, 0 stopped, 0 zombie
Cpu(s): 4.0% us, 0.7% sy, 0.0% ni, 0.0% id, 95.3% wa, 0.0% hi, 0.0% si
Mem: 516416k total, 504260k used, 12156k free, 38204k buffers
Swap: 522072k total, 752k used, 521320k free, 148256k cached

Can someone tell me what /95.3% wa/ in Cpu(s) line means?

Thanks,
Mitja
