            Bug ID: 264267
           Summary: UEFI Booting on Azure Generation 2 VMs crashes
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: mbaptist.opensource@gmail.com

=EF=BB=BFI'm working on getting FreeBSD working on Microsoft Azure Gen 2 VM=
 support and
hitting some issues. I have all of kib's latest relocatable kernel code he
committed in 13.1 (LA57 page table), and seem to have no UEFI booting issue=
s on
KVM or other platforms.

Azure Gen 2 however crashes or stalls during SYSINIT and doesn't go to debu=
gger
or anything. So far I can see it crashing during sysinit via printfs and am
rebuilding now with VERBOSE_SYSINIT=3D1 to see if I can identify a specific
sysinit module.

Hoping this bug makes it to right people, or someone can shoot me a few
pointers on what I could do to further debug this. I'm new to kernel
development in general, but have poked around on my system enough to unders=
tand
the basics of navigating the src tree and have taken some basic os classes =
so
hoping I can figure it out with some help if someone doesn't beat me to it.
