(In reply to Peter Eriksson from comment #18)

I had a problem where FreeBSD 15 rebooted after showing EFI framebuffer
information (no freeze like in this bug).  Thanks to this bug report and
especially Peter's note about serial console, I managed to track that down to
an invalid hw.uart.console value created by loader when serial console
redirection is off.

Unsetting hw.uart.console in loader or using a value from when redirection is
enabled allowed my system to boot.

I reported that as bug 292206 (with a suggested single line fix in a pull
request).
