I do that, the line "script has startet/ended, file is $whatever" comes
from the script-command, which starts a shell and records everything
that is printed on the screen. I do not start a shellscript for the
commands you give me.
So maybe we are near the root of the problem? :-)

It wasn't modified, but I tried to set the min_speed and max_speed
variables manually, unfortunately that doesn't help. :-(

Did that, results are attached.

I may forgot to mention it, but this isn't my first install of Fedora 14
on this machine: I had Fedora 14 before and it worked pretty well, then
I accidently deleted the root-partition and after reinstallation I got
the discussed Problem. So CPU works, BIOS stayed the same, too. (But I
will try to do a BIOS-Update)
