Hi @Bearbobs,

I suggest you install another kernel, for example 5.4:

sudo mhwd-kernel --install linux54

Then reboot, and see what happens at boot.

It’s a good idea to keep 2 kernels anyway, so that if something goes wrong with one, there’s always another one you can use.

Adding to what @Mirdarthos said, remove unneeded/unsupported kernels:

sudo pacman -Rs linux57 linux58

There are remnants of old kernels in /boot - remove them manually:

$ sudo rm /boot/vmlinuz-5.[78]-x86_64 /boot/initramfs-5.[78]-x86_64.img
$ sudo update-grub
