Re: Microfreezes with 6600 GT
Sorry I forgot about this forum for a time, the problem was "kind of fixed" in the meantime.
It seems that certain gnome applets which test for net activity caused this. Each time they polled the OS it made these microfreezes (but eg: top didn't report much activity).
It's possibly a kernel weakness or driver problem or just very short spikes in CPU usage. I ktraced one of the applets and it did loads of syscalls in a loop each time which would cause some ugly context switches.
In any case, removing the problematic applets (gkrellm btw works ok so it's a design issue with the applets I guess) helped.
