(dmesg at bottom)

I've hit this twice in the last hour, and the chain appears almost
identical. I'm trying to make build /usr/src, with cvs update -dP done
last night. There are some caveats that should be eliminated first, but
I am not sure how to do so.

1) The install is RC2, but the MP kernel is RC4. Yes, I know this is not
ideal, but I'm trying to build a compete userland to get up to date. The
only installed packages are 1.6.1 pico and tcsh; the rest is RC2.

2) I tried 
./build.sh -O /usr/obj -D /usr/NetBSD-new-build -T /usr/tools build

first, on the single processor GENERIC kernel. It ground away for 15
hours before failing due to a full file system. I'm not entirely sure
why this occured, as /usr was only 22% full. However, / was 95% full, so
perhaps it ran out there. This was with RC2. I have freed up some space
on /, so I can run it again but it'd take 15 hours to fail again, or
not. The main point is that / has restricted disk space (I used the
default partitioning scheme).

I installed the RC4 MP kernel and redid the ./build.sh command. It
ground away for about three hours before getting the panic. I then did
make build and it lasted about an hour, maybe less.

3) I'm not familiar with this environment yet, as part of this was to
get that experience, and the other part was to be able to compile the
macppc kernel (I need to hard wire my ID 6 hard drive to sd0 so it
doesn't get confused with the NetBSD install on ID 0). Some of the
problems could be due to my own ineptness.

I've included df -a at the bottom of this. I wasn't able to capture
the precise message at the panic, but I've included the dmesg and it
has a bit of info that I'm hoping will tie together with bt. I'm not
completely sure if this is precisely the right forum, but it seemed like
a good place to start.

thanks,
tim
