https://doc.opensuse.org/documentation/leap/reference/html/book-reference/ch...
e.g.
zypper in --oldpackage kernel-default-5.3.18-59.19.1 kernel-default-extra-5.3.18-59.19.1 kernel-default-optional-5.3.18-59.19.1
rebooted several times but at least these older kernels also only showed exactly five active cores. Went into the bios then, this is all old hardware, but never messed around in there before, and there was some kind of hardware unleashing mode, activating that and turning it back and forth, even shut down the whole machine into like almost a real cold start, booted back up, and suddenly the older kernels and also the newest one are all now showing all 6 cores as active and alive. So its just fine again. Very weird, sorry for bothering, dont know what happened or why this system acts like this. Never observed only 5 cores before, or I cant remember having this kind of problems in the past.
