Description :
Marcelo E. Magallo (marcelo.magallon@xxxxxxxxxxx)
reported failures on the xfs/stress tests: 026, 028, 046, 047.
On inspection of the ???.out.bad files it appears that
xfsdump/xfsrestore is unable to read the online inventory
data.

This is reported for a SuSE 7 box with:

=======================================================


My next step is to determine if there is a problem writing
or reading from the inventory files.
I will get Marcello to send me the inventory files and see
if I can read them locally.
I might also see if it is worth adding some more diagnostics
to xfsdump/xfsrestore in the inventory code.

This inventory problem has never been seen locally.
