0.8.0: Kernel panic following "ventoy map data is invalid, get from resource"

[buttonmarkederase]

Describe the bug
Was able to boot and install helloSystem in VirtualBox, but when trying to boot on bare metal, it will load up the freebsd logo, stay there for about a minute, then reboot the laptop.

Expected behavior
A live environment booting to the desktop.

Version (please complete the following information):
FreeBSD-13.1 (0.8.0)

Computer (please complete the following information):

• Device: MSI GV15 Thin 11SCV

Hardware:

• Intel i5-11400H
• 8GB ram
• Nvidia GTX 1650 Mobile

Please boot in verbose mode and see if you can determine where it gets stuck.

[buttonmarkederase]

After booting in verbose mode, it reboot again, but much faster than if it showed the logo (rebooted in a couple seconds rather than about a minute)

[probonopd]

We need the last thing it prints on screen.

[probonopd]

Thanks, this is very helpful. It seems to be tripping over the Ventoy kernel driver. Are you using Ventoy? (If you don't know what it is, then you are not using it.)

[buttonmarkederase]

No, I'm not. I wrote the iso to a usb drive using dd on Ubuntu

[probonopd]

A kernel stack trace indicates a NULL pointer dereference in geom_ventoy, function g_ventoy_taste().
So this appears to be a bug that should be fixed in the Ventoy kernel module.

[probonopd]

Currently, geom_ventoy is being loaded for all users, even for those who are not using Ventoy.

Can we find a way to only load the Ventoy kernel module if something (what?) tells us that we are booting through Ventoy?

[probonopd]

https://www.youtube.com/watch?v=HX4q8mHOtoY shows another example of this:

[probonopd]

As a workaround, try

unset geom_ventoy_load
boot

at the bootloader prompt.

To get to the bootloader prompt, press backspace early in the boot process. In 0.8.1 or later, press backspace as soon as the screen becomes all gray, then press escape.
