Hi Mate,


thanks for your follow-up.

It's a Lenovo Thinkpad E595.

I upgraded to the latest 1.29, no change regarding this issue.

It's disabled.

It's a 512GB NVMe SSD. There are two partitions:

1. The EFI system partition (289MB)
2. A LUKS encrypted volume (rest)

The LUKS volume contains an LVM2 PV, with LVs for the root filesystem (which includes /boot) and swap.

Before this I tried booting a Debian kernel image instead of a self-built one, and that booted fine. That seems to rule out an LVM or LUKS related issue. Should have tried this earlier. :(

My working theory is that it's due to some kernel build configuration change in my self-built kernels compared to Debian ones. I'll try narrowing it down, though if you happen to know of any kernel build configuration no longer supported with GRUB 2.12, that might be helpful.
