Update kernel and was wondering if this is good news or not

Support Kernel
1

Hello,

Today I was reading somewhere that kernel 5.14 and lower aren’t supported. Went to 5.15 rebooted and everything seemed fine. Ran sudo mhwd -r Linux510 and got this output

nvme0n1 is where grub was installed. I haven’t rebooted so I was asking here to be safe.

You should install more than one kernel.
E.g.: 5.15 and 5.10.

The last line /usr/bin/grub-probe: warning: unknown device type nvme0n1. can be ignored.

3

Uh … just to note a few things:

Dont attempt to remove the running kernel.
(ps - check running kernel with inxi or uname -a, etc)

Not true. 5.14, 5.13, 5.12, 5.11 are all EOL … but 5.4 and 5.10 are LTS and still supported.
While this is upstream and doesnt match perfectly, here is the kernel page: kernel.org

4

Can I go back and install 5.10? Would that mess anything up?

5

Ok I should be safe then? I’m on 5.15

6

You can have 5.4,5.10,5.15,and 5.16 is experimental/development/new.
I always suggest folks keep at least 1 good working LTS plus whatever ‘newer’ kernel they are trying out.

7

So to install the LTS do it the same way as i did 5.15 mhwd?

8

Yup … I would suppose given your previous posts that you are aiming to have 5.10 and 5.15 ?

  • view current running kernel
    uname -r
  • check mhwd installed kernels
    mhwd-kernel -li
  • install desired kernel
    sudo mhwd-kernel -i linux510
  • remove unwanted kernel
    sudo mhwd-kernel -r linux513

As with most things you can also check the help flag:
mhwd-kernel --help -or- mhwd-kernel -h

9

side note: if you don’t actual intend to set a console font at that level, you can remove it from the list of hooks to use in /etc/mkinitcpio.conf and stop seeing the error.

10

Is this for me as I am the OP

If it is this is what I have for my hooks

HOOKS="base udev autodetect modconf block keyboard keymap consolefont

Which one do I remove?
