Backward-incompatible GRUB2 change causing BIOS setup bootloop
(op-co.de)
Exactly one year ago, after updating a bunch of Debian packages, my laptop stopped booting Linux. Instead, it briefly showed the GRUB banner, then rebooted into the BIOS setup. On every startup. Reproducibly. Last Friday 13th, I was bitten by this bug again, on a machine running Kali Linux, and had to spend an extra hour at work to fix it.
