Ever since Buildroot 2021.02.1 and up until 2021.02.5, the resulting image does not boot any more - the boot process either gets stuck right after displaying "GRUB loading..", or it reboots at that point, leading to an infinite boot loop.

Only known issue was 'Bug 13586 - grub failure with BR2_OPTIMIZE_3' (see [1]),
but should be fixed by commit 'boot/grub2: workaround breakage with -O2,
-O3 build' (see [2])
Regards,
Peter
