This indicates a corrupted log record is being incorrectly parsed.
Please try adding the patch I posted yesterrday that fixed a
fs-fuzzer triggered occurrence of the same oops....

http://oss.sgi.com/archives/xfs/2008-09/msg00296.html

This patch will prevent the oops, but you'll still need to manually
repair the damage to the FS.

Cheers,

Dave.
