Arch Linux

Description:
The grub.cfg file created by grub-mkconfig does not contain the kernel image file reference after the intel microcode image reference on linux system(s) in the initrd line for other than the base system on multiple system booting on i686.

May or may not be related to " FS#43461  - [os-prober] grub-mkconfig fails to place /intel-ucode.img in added system in multiboot." which make a similar error on amd64 systems.

System panic when attempting to boot from other than base system.
