>Description:

I tried to install NetBSD-current/i386 on an older PC (c. 2003 vintage
Intel Celeron) because I wanted to try to reproduce an unrelated bug
on a uniprocessor system, and all my new machines are multiprocessors.

It hung while booting the kernel on the install media after printing
the line "drm: initialized overlay support".  I'm unable to break into
ddb using the keyboard.

This is using the onboard Intel graphics.  The board also has an AGP
port, but it is not in use.

Since the system doesn't boot, I can't extract a full dmesg, but I
have a photo of the last 24 lines which I can make available on
request, and below is the dmesg output from the NetBSD 4.0 install
kernel, which boots fine.
