This is Debian - we carry on supporting hardware until it's turned to
rust (well almost).  Anyway if GRUB is complaining then the kernel isn't
running yet, is it?

I'm reassigning this in the hope that GRUB maintainers can debug it.
However, the bug reporting instructions for GRUB say:

They will also want to know:
1. The contents of /proc/mounts, /boot/grub/device.map, and /proc/mdstat
(if present)
2. Listings (ls -l) of /dev/disk/by-id and /dev/disk/by-uuid
3. Output of 'debconf-show grub-pc'
