Urgh.............

Thanks for the report. Could you provide some more details?

 - Is your machine definitely bricked?
 - Exactly which Dell machine is this?
 - What were you doing to cause your machine to not boot? Using
   efibootmgr?
 - Please send your .config
 - Have you reported this to any BIOS engineers to confirm the cause of
   the bricking?
 - Have you got a dmesg from the machine before it broke?
