N/A - can't boot NetBSD current
>Description:
There are actually three issues I've become aware of with testing NetBSD on this PC, based on the Gigabyte N3150N-D3V motherboard:

* NetBSD current fails to boot as far as the login prompt

* I failed to install NetBSD 9.2 in UEFI mode on it. I had to use BIOS/compat mode and do a BIOS install. I was unable to install current directly so I installed 9.2 then upgraded to the current kernel to confirm it is a kernel issue.

* This machine uses a braswell iGPU. Under NetBSD 9.2, X failed to start via VGA and DVI. The framebuffer console works under 9.2 but I suspect its failing under current when it tries to switch fb console video modes during boot. I know X is installed OK because I took the same disk, installed it in a PC with a NVIDIA GPU and it booted it and ran X fine.

This ticket is mainly for NetBSD current failing to boot but I can open tickets for the other two issues if required.

I can provide a screenshot of the console output at the point where the boot fails but there doesn't seem to be the ability to attach files to bug reports on here so maybe I'll email it to whoever picks this bug up?
>How-To-Repeat:
Try to boot NetBSD current on a Gigabyte N3150N-D3V.
