DMA disabling and system permormance was tested now with launching the following
command:
hdparm -d0 -B 255 /dev/hda

Result was a stable system. Speed slowdowns are minimal. Changing the
/etc/hdparm.conf accordingly did not help for bypassing the problem however. The
kernel ignored the commands of hdparm.conf, thus hdparm -d0 -B 255 /dev/hda
needs to be launched from a terminal after every login.
