Hello Ken,

thank you for the answer!

Before i start to debug the kernel versions i tried to find other problem reportings for this mainboard.
And i found them! http://napalmpiri.info/tag/freeze/
Yes - this is uncommon hardware!

It seems that this mainboard type is a slip from normal Asrock quality.
Specially the BIOS seems to be buggy and have never been fixed complete. :-(

The solution seems to be: never change a running system when you have one. :-)
But after a couple of years you must change it, specially when parts are broken.

Maybe i will try this.
But currently i think it is not a bug of the used chipset.
This mainboard has a bad BIOS and the last update is from 2011.
There is no hope that the problems will be fixed. :-(

I could reactivate an old backup with Debian wheezy and kernel 3.2.
This i running stable on this mainboard and i think it will be the latest release that is usable there.
