System slow when using updated kernel

[Luis A]

System is slow when using kernel version 5.8.0-20-generic. (Low fps in desktop, boot takes more time, opening any application takes seconds)

A temporal fix is use old kernel.

Since Apport did not have a system related category, I have to report it here. I dont know how to gather more information about my system.

//Output of 'lsb_release -rd'
Description: Ubuntu Groovy Gorilla (development branch)
Release: 20.10

//Output of 'lshw'
Processor: Intel(R) Core(TM) i3-6006U CPU @ 2.00GHz

Also, resources are not at 100%, I have a SSD, 8GB RAM, is overkill for just using the system.

Is this still problem with 5.8.0-23-generic?

ProcCpuinfoMinimal.txt shows low frequency. Last line is empty:

Could you attach /proc/cpuinfo from working kernel?

How can I update the newer kernel form my old and working kernel, without touching my working kernel, so if the update does not fix the problem, I can just still using the old kernel. Also, thanks for your time, as a open source developer I know this is not easy.

[Jouni Mettala (jouni-mettala)]

I can see known bad kernel in description. However you forgot to name known good one.

1. Please tell us known good kernel.

2. Package: linux (not installed) It looks like you disabled kernel updates somehow. Could you re-enable them again? You can sudo apt install linux-[known good one] so that autoremove doesn't remove it. At least bad ones boot for you. They have security updates.

3. You have pci=noaer kernel parameter. Did you add that yourself?

[Luis A (peppapig123)]

Good kernel: 5.4.0-45-generic
pci=noaer fixes bug #1521173
I will try to update things from the bad kernel, it will take a full day to do it, but I will try It.
Also, before knowing what was the problem, I tried to disable all updates from Software Updater. I will enable It and install all updates one of these days.

[Jouni Mettala (jouni-mettala)]

You can select older kernel in bootloader.

[Jouni Mettala (jouni-mettala)]

Could you test https://wiki.ubuntu.com/Kernel/MainlineBuilds
Similar bug seems to be fixed upstream.
