Hi, It look like there is a grub regression when using grub2-2.02-rc[12] with a bios in MBR mode and GPT partitioning:
Grub does not give the boot parameters to the kernel that did not find the root partition although that the partition with the good PARTUUID is listed before the panic and that everything works when the bios is switched to the EFI mode (i haven't this issue with the 2.02-beta2 version). You can get more details here: https://github.com/lede-project/source/pull/1026 Tests where made using LEDE and Virtualbox. Partitioning : sda1: ext4 (4 MB) - /boot/vmlinuz - /boot/grub/50092577.cfg - /boot/grub/grub.cfg serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1 --rtscts=off terminal_input console serial; terminal_output console serial set default="0" set timeout="5" search --file /boot/grub/50092577.cfg --set=root menuentry "LEDE" { linux /boot/vmlinuz root=PARTUUID=09BBA8CF-313E-420B-B5A8-E6B13DE60002 rootfstype=squashfs rootwait console=tty0 console=ttyS0,115200n8 noinitrd } menuentry "LEDE (failsafe)" { linux /boot/vmlinuz failsafe=true root=PARTUUID=09BBA8CF-313E-420B-B5A8-E6B13DE60002 rootfstype=squashfs rootwait console=tty0 console=ttyS0,115200n8 noinitrd } sda2: EF00 vfat (1 MB) - /efi/boot/bootx64.efi (grub) - /efi/boot/grub.cfg search --file /boot/grub/50092577.cfg --set=root configfile /boot/grub/grub.cfg sda3: EF02 raw (1MB) - grub modules sda4: ext4/squashfs - the rootfs with the GPT PARTUUID : 09BBA8CF-313E-420B-B5A8-E6B13DE60002 Best regards, DUPONCHEEL Sebastien _______________________________________________ Bug-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-grub
