More than 10 seconds Particularly after you've closed the > lid but before unplugging the adapter. More than 10 seconds, just because this is the use case where I first saw this problem. I close the lid, unplug the adapter, put everything in my bag, go to another place, plug the adapter back in, and then open the lid. > Without the revert if you follow this (specific) timing does it still happen? > > 1) Close lid > 2) Wait 10 seconds > 3) Unplug adapter > 4) Wait 10 seconds > 5) Plug in adapter > 6) Wait 10 seconds > 7) Open laptop, check frequency The frequency problem occurs: - 544 MHz in power save mode, with some spikes to 1101 MHz; - 1101 MHz in performance and balanced profiles, with some cores occasionally dropping to 544 MHz. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2088733 Title: low CPU frequency after wake up AMD Ryzen To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/2088733/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
