 Posted: Sun Dec 20, 2020 8:08 am Post subject: [SOLVED] Kernel > 5.4.48 doesn't find BTRFS root |
 |
|
Hi All,
Using a Kernel > 5.4.48 leaves me with a Kernel Panic unable to mount root fs. All configs are same (just done a make oldconfig).
Choosing the 5.4.48 entry in grub boots the old Kernel without issues.
Root Files System is a NVME BTRFS format.

Solved by switching to PARTUUID instead of UUID solved the issue. Not sure why the Kernel change caused this but at least solved.
Solution:
In /etc/default/grub set GRUB_DISABLE_LINUX_UUID=true |
