The head and tail of the log are confused - different cycle numbers
but the tail is behind the head. That implies that there are 3 cycle
numbers visible in the log, when here should only be 2, which would
mean that some log write did not make it to disk correctly.
You'll need to provide a copy of the log (xfs_logprint can get that
for you) and the information about your system described here:

Cheers,
