Which is somewhat scary, the oops happened here;


void
xfs_trans_unlocked_item(
         xfs_mount_t     *mp,
         xfs_log_item_t  *lip)
{
         xfs_log_item_t  *min_lip;

         /*
          * If we're forcibly shutting down, we may have
          * unlocked log items arbitrarily. The last thing
          * we want to do is to move the tail of the log
          * over some potentially valid data.
          */
         if (!(lip->li_flags & XFS_LI_IN_AIL) ||
             XFS_FORCED_SHUTDOWN(mp)) {
                ^^^^^^^^^^^^^^^^^^^
                 return;
         }

Which makes it look like the mount structure has been freed.

I notice the kernel is tainted, what was loaded?
