Foolowing up with the  tests on hardware Adaptec RAID with XFS, I got
this bug when running mount on a corrupted XFS volume:

Configuration: kernel 3.17.7, amd64 on Debian 7.7. The hardware is
unchanged from my previous tests ( Adaptec 71685, dual Opteron 6212).

The filesystem got corrupted while rebuilding the RAID and doing
read/write IO, as previously. There is first this error:

It goes on a bot more then it becomes that:

It goes for a long time, then that follows when I unmount and try to

The double free oops part of this bug was my fault and fixed as part of 
a log recovery reorganization:

commit 88b863db97a18a04c90ebd57d84e1b7863114dcb
Author: Dave Chinner <dchinner@redhat.com>
Date:   Mon Sep 29 09:45:32 2014 +1000

     xfs: fix double free in xlog_recover_commit_trans

     When an error occurs during buffer submission in
     xlog_recover_commit_trans(), we free the trans structure twice. Fix
     it by only freeing the structure in the caller regardless of the
     success or failure of the function.

The original corrupted metadata is probably caused by your RAID.

Yes, probably. But the part with "kernel BUG" probably isn't :)
