I just found out something and would like to add:
Sorry for being misleading, I checked the kernel version I am using now
and actually the instability was with the AMD.
With the Intel hw the machine seems to be stable with the RT kernel,
so what I said above is not valid for the Intel configuration, I had
the problems with
the earlier hardware.
