In case of Arch Linux when kernel updates it deletes all initramfs and 
vmlinuz related to that kernel just before the update.

Via: /usr/share/libalpm/hooks/60-mkinitcpio-remove.hook

So when there is update to linux as well as linux-lts and something 
happens while upgrade is running, none of the kernels will boot.

So best way is to, update each kernel separately. (I normally use pacman 
-Syu --ignore 'linux-lts*')
