Hi everybody,
I got the hardware back from the HP support. The support confirmed that
there has been a hardware bug in the motherboard of the system.
The motherboard has been exchanged. I have now installed Fedora-19-Mate
and everything works ok.
Hence this is most probably not been a Ubuntu or Linux bug. This bug can
be closed.
By the way: The support by HP has been very helpful allthough the bug
appeared in Linux and this is offically not supported
Thanks for everybody for the support!!!
