Hi @P1000,
You can check perform kernel installation, checking and more with the mhwd-kernel command:
To list all installed kernels:
$ sudo mhwd-kernel -li
Currently running: 5.10.7-3-MANJARO (linux510)
The following kernels are installed in your system:
* linux510
* linux54
To list all available kernels
$ sudo mhwd-kernel -l
available kernels:
* linux414
* linux419
* linux44
* linux49
* linux510
* linux511
* linux54
* linux59
* linux54-rt
* linux59-rt
To install a kernel:
$ sudo mhwd-kernel -i <kernel_version>
For example:
$ sudo mhwd-kernel -i linux419
