The fuddling starts suddenly and nothing specific happens apart from
that after some time there isn't any space lest on the root file system.
I'm not a kernel expert but it seems to be associated with the
scheduler. It occured before, then stoped after some updates (probably
after updates just the problem didn't occur) then today (I had to reboot
because it continuously logged the messages ant the files where growing
rapidly.
If any other information are needed I have the whole logs (maybe not
whole just 25MB out of 900...) and I can post more of it.
