Maybe there was something wrong with ACPI or something and saving the firmw= are settings fixed them=E2=80=A6 Interesting that it didn't affect Windows 10 t= hough. (In reply to Eric van Gyzen from comment #2) Desktop Ryzen is not NUMA, it only has one domain. Threadripper has two domains, EPYC has four, but Ryzen only one. It has some 'NUMA-like' cache groups as recognized in 'FreeBSD/SMP: 1 package(s) x 2 cache groups x 4 cor= e(s) x 2 hardware threads', but this is not actual NUMA. --=20 You are receiving this mail because: You are the assignee for the bug.=
