Description Austin Shafer 2023-03-02 18:20:23 UTC 
I'm having issues getting past the loader stage while trying to boot a GENERIC-KASAN kernel on a Legion 5 laptop (FreeBSD 14.0-CURRENT #1 main-n261043-357492c99597). The kernel is loaded, zfs.ko is loaded, then it hangs for a few seconds and prints out:

efi_check_space: Unable to expand staging area

This gets printed a couple of times, then the EFI frambuffer location is printed, then the boot hangs.

I've tried bumpin the EFI_STAGING_AREA size to 512, and also to a ridiculously high number, but that doesn't seem to do anything. I also tried reverting the fix for PR 265019, but that didn't change anything either.

Any suggestions? Anyone else seeing something like this?

Do you have an up-to-date copy of the EFI loader installed?  In particular, you'll want to have at least https://cgit.freebsd.org/src/commit/?id=9a964ad56182740ea09b87f7e6db4197c6756e48
