knowledge on this subject), I am now facing "invalid signature" error when I reboot with my installed dev kernel.
When/where exactly are you getting that error? There's three major places where things can go wrong: 1) If you're using secure boot, and the grub2 stuff isn't signed by a certificate your BIOS/EFI knows about. 2) If you're using secure boot, and the kernel itself isn't signed by a certificate that grub2 knows about. 3) If your kernel config says modules have to be signed, and a module isn't properly signed with a certificate that your kernel knows about.
