I’m running Kicksecure on Lenovo T560 ever since the install two of the CPU cores have been offline.
Is there a way to fix it so i can use all of my cpus. (no modifications have been done on laptop or kicksecure, both used as is, only virtualization enabled in bios)
I tossed bunch of commands suggested by GPT here are the results:
