I as the thread starter fully agree with Borislav and set this bug report to status resolved. Thank you all very much for the interesting discussion!
Having started with massive stability problems on my new Ryzen build, I reported this issue to address a potential problem in the Linux kernel. In the hundreds of comments, which surely could be very interesting for everybody affected, I found a workaround - disabling C6 states with the python script attached to a comment above. Since then the system was perfectly stable. Test with the "kill Ryzen" script also showed me, the CPU was not affected by the other huge problem early adopters had. A few days ago I finally found the time to update the AB350 BIOS to the latest version and set the "typical idle current" in the options. I had only 2 issues since then: The bootloader entry for my OS was broken after the update and network manager did not bring up the LAN interface anymore. But after resolving these issues: No more stability problems. Of course I deactivated my systemd service for c6 states. I am still on the stable branch of Manjaro and use the latest 5.5 series kernel.
