Hi all!

Please help me at least to understand the reason, and better to fix a bug (?) decribed below.

I found on fresh installation of Kubuntu 9.10 x64 (kernel 2.6.31-19-generic) that CPU load is laying between 70-90%, sometimes - 100%, while in BOINC Manager's settings said to use 100% of processors and 100% of CPU time.

I have tried a realtime kernel, but the situatuon was even worse on it - about 50% of CPU load sometimes, and not for short period... (Actually, I even don't know exactly, what is it maid for - it was just an attempt to fix this issue and to see, what will happen... :-))

Note that no other applications are not running when I observe CPU load...

What should I do to have a constant 100% load, as under Windows OS before?.. Because it seems that Kubuntu just allows CPU to be idle for a part of time while it's so needed by BOINC...

Thank you in advance!
From Siberia with love!
