Re: black screen, boot doesn't finish

[Matthias Petermann <mp%petermann-it.de@localhost>]

Hello all,

I have here an Intel NUC i5-7300U with integrated graphics with similar 
problems on NetBSD 9.99.93 (build from 02/28/2022).

When I boot the machine in UEFI mode, the green kernel output appear 
first, until the mode switch of the graphical console. After that the 
screen remains black.

When I boot on the same device in BIOS mode, it continues properly after 
the mode switch to graphical console.

Is there a patch etc. that would be worth testing?

Many greetings
Matthias
