Error: Failed to Load Kernel modules after Kernel upgrade

[deroberts1]

After clicking to upgrade my installed kernels the system does not boot. I get an error saying failed to load kernel modules. I rolled back with Timeshift to get everything running again with no problems.

I have the LTS kernels installed and right now I am running in kernel 5.4.85-1.

Here is the output of

pacman -Q | grep -e linux54 -e linux41

linux419 4.19.163-1
linux54 5.4.85-1
linux54-nvidia-340xx 340.108-80

What do I need to do to fix this error? Is this the NVIDIA driver issue?

Failed to start Load Kernel Modules - after update

I had the same error. It turned out to be NVIDIA-related. At the error, press CTRL + ALT + F2 to get into tty. Log in. This is what I did to fix it: My card is not old GTX1050Ti. Execute, mhwd -a pci free 0300 I used pamac to remove any existing NVIDIA drivers, and then used pamac search -r nvidia to find the latest drivers (460.32.03-3). I installed the linux54-nvidia package because I’m running the 5.4 kernel. You may also need nvidia-utils. If you are running older hardware, you may nee…

Looking at my driver situation it looks like I should switch to the Nouveau drivers as my 8400GS supports only the 340xx series.

I assume I should switch to Nouveau before I try another kernel update. Right?

All good now. I removed the Nvidia drivers, including all the config files. Then I updated the kernels and rebooted. It booted without error now. So I pressed ctl+alt+F2 to get a tty.

Next, I typed modprobe nouveau and the GUI started right up. The system seems just a fast as before and I see I am using less memory now.
