I'm experiencing the same issue on a Thinkpad T590 (with a i7-8565U CPU @ 1.80GHz).
With kernels up to 5.8.0-55, the CPU frequency rarely exceeds 1200 MHz, most of the time it stays at 400 MHz, even in high-load situations. Even regular web browsing brings the system to its limits, let alone compiling code. With kernel 5.4.0-74, everything works fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901406 Title: Lenovo T490 extremely show with Ubuntu 20.20 running kernel 5.8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1901406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
