Sorry the server is not booting, so I can't do a uname -a.
It's a i386 processor under qemu

I'm sorry that I can't follow as I did not get any pc = 

I got a KP when booting NetBSD 4.0.0 or one 
under QEMU. I did not have much information about QEMU configuration. This is a 
server hosted by a french company ( They allow customers to boot their 
server using QEMU to get a sort of virtual KVM on the server.

note that the trace come from the 200805250002Z iso but I got exactly the same 
with 4.0.0 iso but address may be different
You can get the 200805250002Z iso at if the iso is 
no longer available on netbsd ftp server when you read the pr
Every thing work fine if I boot NetBSD 3.1 iso

When booting I got this :

You can see the full dmesg view here: files Image 1.png  Image 
2.png  Image 3.png and  Image 4.png
I think that you will not be able to reproduce easily :/
I will try to get more information about QEMU configuration but not sur that I 
will get them
