Errr...  I'm at a loss as to how you could have gotten this error message.

There is no assertion like that in inode.c.  The timestamp that GFS
printed out "time = 1095145469" is no where near Oct 24 11:04:29.
The panic message looks suspiciously similar to one posted in
September when someone forgot to recompile their lock_harness module.

Maybe you had a cut-and-paste error?
