Bug#1036041: upgrade-reports: Dell XPS 9550 fails to boot after bullseye to bookworm upgrade - grub/bios interaction bug?

[Jens Yllman]

Hi,

This seems to have happened to me too. But I just upgraded my Debian 
unstable around the 5th of May and got a grub update. After the upgrade 
I could not boot into Debian again. When I tried it just failed into 
memory check and reboot.

I have an Dell XPS 15 9560.

Setting GRUB_TERMINAL=console and running grub-install and update-grub 
got the system up and running again.
