But there seems to be more reports of TRX40 users who are having the same problem: https://forum.level1techs.com/t/is-there-cppc-support-on-threadripper-3000-= platform/195804/5 https://www.reddit.com/r/threadripper/comments/151l6rn/threadripper_amdpsta= te_driver_on_arch/ https://www.reddit.com/r/linux/comments/15p4bfs/comment/jvvr12s/?utm_source= =3Dreddit&utm_medium=3Dweb2x&context=3D3 A while ago I was running a custom Xanmod kernel which had the amd-pstate patchset applied before it was sent upstream. It was an older revision of the driver of course but it was working for me. The only requirement back then was setting the "shared_mem=3D1" flag on the kernel command line. But this flag doesn't seem to fix it for me when running linux 6.5. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are the assignee for the bug.=
