Comment 5 for bug 334577

I am using Kububntu 20.10 on a HP Spectre x360 15-ch004ng. It has Kernel Version 5.8 installed and does not correctly access the cpuinfo frequency parameters for my CPU, which is an 8xIntel Core i7-8705G CPU @ 3.10GHz.

I decided to try booting 20.10 into recovery mode and then entered the console. I found that cat/proc/cpuinfo | grep "MHz" gave the correct results. I took a photo of it and this is shown in the attachment.

When I reboot, it then shows the /proc/cpuinfo frequencies in MHz with a string of 800's, ie

:~$ uname -r
5.8.0-18-generic
:~$ cat /proc/cpuinfo | grep "MHz"
cpu MHz : 800.072
cpu MHz : 800.012
cpu MHz : 800.123
cpu MHz : 800.196
cpu MHz : 800.009
cpu MHz : 800.143
cpu MHz : 800.062
cpu MHz : 800.086

I am not sure how much of the Kernel is loaded at the recovery stage, but it appears that the problem with not getting the correct CPU Info occurs after this point.

The end result is a very slow desktop. This is solved by installing Kernel Version 5.4.0-42
