ok, some progress - looks like the scratch device problem is
resolved and test 002 is fixed - great!

004 - this looks like a 32 bit number overflow in the xfs_db
"freesp" command, i'll need to investigate a bit more.

018 - ??? no idea - looks like theres a bunch of unexpected
records in the log for some reason?  bizarre.

020 - attribute syscall code not there in ppc?

026/027/028/046/047 - a reoccurence of the dump/restore problems
from Marcelo, Tim/Ivan?  or new ones?
also group "nobody" assumed to exist, but doesn't.  can we change
the way the test works, Tim?  or exit cleanly if no "nobody" grp?
or use numeric gids instead of named groups perhaps?

032 - hmmm... could be a problem in mount(8) code which we use
for mkfs.xfs so that it doesn't overwrite other filesystems -
can you see whether mount on ppc can autodetect (i.e. mount
without "-t" a filesystem created by mkfs.minix on ppc?  thanks)

033 - stress/src/devzero is not doing whats expected of it for
some reason? (the "Wrote 0.00Kb messages are very suspect, the
rest looks like consequential failure)
