Hi, please find below a list of related bugs to a blocker that affects existing systems and even prevents the installation of several Linux distributions: https://bugzilla.kernel.org/show_bug.cgi?id=199267 https://bugzilla.kernel.org/show_bug.cgi?id=201129 https://bugzilla.redhat.com/show_bug.cgi?id=1608242 I read about an upstream fix to 4.20 but this is a long way to go. I guess that anyone who keeps their AM4 BIOS AGESA Code update-to-date and would like to run Linux is affected. A co-operation between AMD & Linux Kernel experts to achieve a solution fast is encouraged. Thank you! Regards, Thomas
