I/O Bound Procs Clobbering Responsiveness

[Karel Volný]

Hi,

I'm afraid the problem is not specific to Fedora ... I see 
something similar on my Gentoo box after upgrading kernel from 
2.6.39 to 3.0.6

I haven't tried with USB but I can see whole system being pretty 
slow if there is high SATA load.

And also I had to stop bitcoin computations on my GPU, as the GUI 
became totally unresponisve while running poclbm - this didn't 
happen with previous kernel, I could run the computations in the 
background while working with the GUI.

/me is thinking about kernel downgrade ...
