Yes it is compressed.

Thanks much for this. I did a simple test, I rebuilt a DVD that wasn't
booting to use a lower level of compression (gzip -9 to gzip -6) on
mfsroot without changing anything else. This caused it to boot normally.

I'm not sure it's conclusive evidence, but it certainly looks like a
weak datapoint supporting this kernel bug being the source of my
problem.

Is this problem fixed in 8.0 or by a patch?
