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

Control: reassign -1 src:grub2
Control: severity -1 serious

Hi Tim,

Thanks for reporting the issues your facing. The comments in the report 
suggest this is an issue with GRUB, so I'm reassigning it to that 
package for further triaging.
