Ah -- your 'c' partition does not start at 0.
It's an old FreeBSD partition on your disk.  That should not work; it

is bunk.  We are removing the code from the kernel that allows it to

work, because it requires extra stupid checks all over the place to

support an old 386BSD stupidity.
I hope that our new disklabel command, upon re-writing that label, will

repair that.
Todd?  That's the way to handle this, right?
