Bug Description

I have no further information, sadly. The boot stops at the message "EFI stub: UEFI Secure Boot is enabled". Disabling secure boot or selecting an older kernel both work fine.

Sounds like bug 1844101. Although this bug is newer I feel the details in bug 1844101 are more useful.

Yes, I assume it's the same bug. Julian and I were actually sitting next to each other yesterday trying to diagnose things. As the other bug has logs, let's mark this a duplicate of the other.
