Here's a list I can't remember the last time it worked, if you do a google search on "ubuntu cpu lowest freq" seems to be a very common problem but none of the fixes work for me. I can't change the speed of my CPU's in my bios (a system76 linux machine). What do you want me to check in the bios? Here's the kernel versions rt@sys76:~$ uname --all Linux sys76 5.15.5-76051505-generic #202111250933~1638201579~20.04~09f1aa7~dev-Ubuntu SMP Tue Nov 30 x86_64 x86_64 x86_64 GNU/Linux rt@sys76:~$
