many thanks for your help.
I have done memtests two times before I posted this issue. There were no defects detected.
What did you mean with '..if you have VTd enabled'?
I will now trying the following boot option:
GRUB_CMDLINE_LINUX="i8042.noloop intel_iommu=off"
it can take some days until I will post the results. mostly the freeze now occurs only when I use the external monitor in my office. Working with internal laptop display only the system seems to be quite stable. But I had also one freeze some days ago with in this situation.
