Title:
Lenovo T490 extremely show with Ubunt
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

I just wanted to chime in and say I have the same problem, also with a
T490, although the processor is i7-8565U CPU @ 1.80GHz and I am running
Kubuntu 20.10. Currently running kernel 5.8.0-28.
If there's any way I can help, let me know.

I couldn't find any builds in the 5.10-rc1 folder you linked to, but
instead I tried 5.9.1-050901-generic #202010170731. The performance
seems good and I get frequencies above 3000Mhz, so I think the problem
is fixed here.
I would like to stress that the problem IS NOT fixed in 5.8.16, it's
just m
So far 5.8.14 is known bad version. 5.8.16 is bit better. Could you test
middle point 5.8.15?
Could you also test new upstream version v5.10-rc1?

This seems to work a little bit better than the Ubuntu kernel, but not
