Re: Running kernel does not match the kernel modules inside the nfsroot

Check the file that fai-chboot created. It looks like the kernel line 
does not match the append line for kernel versions.
 From your output the 4.19.0.9-amd64 kernel is booted but the parameters 
refer to the new kernel version initrd file.
Both need to be the same version.
