Hi there,

If you are interested in helping to fix this problem, it would be
helpful to see whether you get stuck booting NetBSD-current, too.

You can grab one of the builds here:
http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/

I'm unsure if this has to do with the graphics card chosen!

Unrelated:

I've used the OpenChrome driver with a VIA M8K800 (onboard).
The fixes that resulted from this attempt are in NetBSD-current.

This isn't the DRM KMS driver (does it work now?), though. it is the
old DRM UMS driver (called viadrmums here).

However I could not see a difference between using it and not using it,
so I'm not sure this is worth the trouble.

It was a matter of adding this line to the kernel config
(sys/ARCH/conf/GENERIC):

viadrmums*     at drm?

and building just a new kernel:
./build.sh -mamd64 -U -u -O../obj tools kernel=GENERIC

Radeon:

I have a HD5430 that works well with NetBSD-current or NetBSD-7-stable,
but was panicing at boot on 7.0 release.

Keep this in mind in case you have trouble further ahead, you can grab a
NetBSD-7-stable in nyftp.netbsd.org as well.

It's also possible to bypass all the trouble if you don't care about
graphical acceleration by disabling radeon at boot. it will still
display things, but it is CPU intensive. VIA graphics will do this, too.
(you shouldn't need to use a second card in this scenario).
