After one year, I am finally using my 2700x without any issues, latest Ubuntu 18.04, Linux 5.0.0-27-generic. No patches, no kernel options. I put the system to sleep everyday and it always comes back when I press a key the next day.
I updated the BIOS of the AB350M-DS3Hto F31, the most recent update before 3rd Gen AMD support was added. I also put a PSU that I had around, a TT-450NL2NK. The one before had less watts. I let the Typical Current Idle option, but I don't know whether it has some effect. I also have a GeForce GTX 1050 Ti now. I changed quite a few things, so I cannot really say what improved my setup. But I want to report that the system is finally stable. Regards. (In reply to Nelson Castillo from comment #399) > Hello there.
