restore hangs filesystem (more in the running-with-scissors saga)

I've got a suggestion to try a dump after copying a superblock that
still exists on the disk to the default superblock location. Is that
0? 32? Anyways, that's just a sidebar.
One of the other disks that failed this week (my laptop drive) is less
sick and the dump succeeded. I now have a 50 gig dump file. Good.
Now I have a machine that's been in production in my home network for a
year or two ... and for this project I added a 250G drive. The 250G
drive contains a single partiton and I formatted it UFS 2 with a 65536
blocksize and a 8192 frag size. I intend to put big files on this disk.
Anyways, I created a directory on that disk (which also contained the
filesystem images and dumps ... about 120G in 5 large files), cd'd into
that directory and ran 'restore -rvf ../dumpfile'. This went along
creating directories for awhile and then it stopped for a few momments
... then sputtered along for another few seconds and then hung. The
other disks on the machine were also hung when I tried to access them in
I rebooted, waited for the background fscks to complete and tried
again. It appears to be repeatable.
The disk that I'm restoreing is a typical laptop /usr ... it has
/usr/ports and /usr/src (many directories).
