Thinkpad T460 with Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz Recently went Ubuntu 16.04 -> 18.04.
Using intel_pstate in default configuration. HWE low latency kernel: Linux machine 5.3.0-62-lowlatency #56~18.04.1-Ubuntu SMP PREEMPT Wed Jun 24 16:57:19 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux For context, this laptop mostly moves from docking station to docking station. It lives most of it's life in "clamshell" mode and is only occasionally actually opened. CPU gets "stuck" at 1.6GHz after clamshell->clamshell suspend/resume cycle. Opening the lid (!!) resolves the issue. Doesn't come back when I close it again. :wtf: I am at a loss for words. Definitely did not have this issue in 16.04. I guess my hinge will be getting a workout until this is resolved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838141 Title: intel_pstate not working.
