>Environment:
NONE. Crashes on installation boot sequence, does not complete.
>Description:
While booting from CD/DVD ISO image install, crashes on installation boot sequence where it says vmbus0: protocol 3.0, then 
uvm-fault(0xc157e960, 0, 1) -> 0xe
fatal page mode in supervisor mode

(I don't know how to upload a screenshot here for you). 
>How-To-Repeat:
Setup as Generation type 1 (BIOS) on Hyper-V on a Windows 11 Pro system (here a DELL Latitude 7490 with 32 GB DRAM), Memory 1GB to 4 GB using ISO CD/DVD image to boot VM, no dynamic memory.

I've been testing several daily images, here is latest:

>Fix:
I do not know how to.
=> Found NetBSD (compared to FreeBSD and OpenBSD) X11 installation is the only one that works on Hyper-V so far.

Same setup as above, but for **NetBSD 9.3 i386** version works excellently well on Hyper-V with 1 GB DRAM, hnv0 network driver, X11, video can show youtube.com videos (no sound, a Hyper-v limitation).

Similar setup but for **NetBSD 10 beta RC1 amd64** version with 1 GB DRAM boots and allows full installation with hnv0 network driver, X11, video show youtube.com videos (no sound, a Hyper-v limitation).

Please help, would like to start development on version 10.
