Thanks very much! Were /usr and /usr/obj on different filesystems
and/or different disks?

1h45m is terrific compared to some of the others, but I can't say that

I've written Colin to ask his opinion. Can anyone else comment on the

What branch were you tracking? I try to note that in both the dmesg
and worldstone info. In the meantime, I've added your dmesg to the
archive as u80_unknown_unknown.
Terrific, Steven -- thanks for testing this!
