Sounds like the experience described in PR 239876. Maybe?

While I’m not successfully booting 12 yet, I use iPXE and sanboot bootonly
ISOs. However, those ISOs have failed with the errors described in the
aforementioned PR since 9.something.

I work around this by building a MDROOT kernel that is installed in the ISO
during make target bootonly.iso. Bear in mind the MDROOT kernel must be
smaller EFI_STAGING_SIZE and the kernel config/environment must define
MFS_IMAGE.

PR 227808 describes how to accomplish this.
