I posted this to port-hpcmips, but got no reply. I'll try again here.
A 2.0.2 kernel boots fine, but when I grabbed the release-3 source via
cvs and built, the kernel wouldn't boot:

I just got done building 3.0_BETA yesterday for hpcmips. I built a
release on an i386 running 2.0.2.

The build was failing for various reasons on my i386 and also on my
amd64 3.0_BETA machines, but I cvs'd the sources every time and
yesterday it finally decided to build completely.

Here are the exact messages on the screen:

mem_cluster_cnt =3D 2
mem_clusters[0] =3D {0x0,0x37b000}
mem_clusters[1] =3D {0x37b000,0x1c85000}
loading 0x37b000,0xc85000

And that's it. It won't boot any farther. Do I need to pass in some
options via pbsdboot.exe, or possibly recompile with some debug
options?

Any help would be appreciated.
