First of all, I put the blktrace and vmstat logs on my webspace because they
grew too big for the list to handle. :-)

http://www.mortal-soul.de/blktrace.log.bz2
http://www.mortal-soul.de/vmstat.log.bz2

Just let me know once you got them, so I can safely delete them again.

At the moment, I am trying without preemption but for example doing a untar
kernel sources still results in sluggish system responsiveness. :-(

If I can do anything else, please let me know.
