Re: install/55478: netbsd 9.0 - Installer freezes on macbook pro late 2013

[Andrius V <vezhlys%gmail.com@localhost>]

I retested my mac and I can confirm that the problem can be reproduced
if booted without ACPI support (-2 option) on any NetBSD version.
However, normal boot (with ACPI support) from official 9.0 amd64 UEFI
image works fine, same applies to the latest i386/amd64 9.0 images
from https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-9/latest/
(latest versions combined UEFI/BIOS boot into one image) or latest
current (HEAD) images. So, it seems there is no point to boot with the
-2 option since it causes some hardware initialization to fail.
Nevertheless,  I believe the initial issue on a blank screen is
unrelated and probably caused by the framebuffer driver(?). Likely the
system boots properly though under the hood. It can be verified by
adding dmesg=YES to rc.conf and checking /var/run/dmesg.boot messages
after (by mounting partition in different system). Still, I would
recommend trying the latest builds from nycdn first, since I had a
similar issue in previous releases too. Also, I don't have NVIDIA
graphics, only Intel graphics.  Maybe disabling nouveau (or even
i915drmkms) can help here, but I am not sure if that can be done
without recompiling the kernel manually.
