Photograph of the bug:
<https://old.reddit.com/r/freebsd/comments/ir90ra/hp_probook_440_g7/gejo49g/> (2020-12-04) observed that a previously available HP ProBook 440 G7:
* did boot from installers for OmniOS community edition
* did _not_ boot from installers for FreeBSD 12.2 or 13.0-CURRENT
* did _not_ boot from the installer for GhostBSD.
From the postscripts there:
> FreeBSD bug 244906 – kernel booted by loader.efi on
> VMware Fusion crashes in EFI firmware
> * discussion in IRC suggests that the
> root cause may be the same
> * Toomas Soome (tsoome) thinks that mine is the
> second hardware instance of the bug.
Bug 244906 became a duplicate of later bug 251866:
> Because the loader.efi modified the size of EFI_STAGING_SIZE,
> vmware could not start the system above FreeBSD 12.2

Adjacent bug 255072 for the same hardware not booting in legacy mode.

>> … Ludovit Koren … HP EliteBook 830 G7.
I can also confirm this issue on an Elitebook 840 G6. Can also confirm it happens both in CSM and UEFI only modes. Both with Secure Boot disabled.
Update to date UEFI firmware as of April 2021.

Does it help to compare with boot failures for NomadBSD?
