https://bbs.archlinux.org – Dear all,Please forgive me if this is not the right place for this post.I had issue for running powertop since its version come to 2.x. Once I launched itfrom the terminal it would return a error message "msr reg not found" and thenthe shell itself behaved very weird, for example the output of "ls" becomecompletely mess. But powertop 1.x worked well on my laptop.I am now running archlinux with linux-ck kernel but I am not sure if this is a kernelrelated issue. I will appreciate very much if somebody could give me any suggestion.Regards,Zhengyu xzy3186 https://bbs.a (HowTos)
