I am using linux kernel 2.6.18 with XFS support.
I have formatted USB hard drive with XFS. When I try to copy
(i.e. cp 1.avi 2.avi) a big file (size : 1.3 GB) from one
location to another on the same hard drive It corrupts the
hard drive with the following back trace.

XFS internal error XFS_WANT_CORRUPTED_GOTO at line 1588 of file fs/xfs/xfs_alloc.c.  Caller 0xc0131a70

But no solution is found.

Can you guide me Or answer the following questions.

1. Is there any patch available which solves this problem.
2. If there is no patch available so far then can you give me
  some pointers which will help in solving the problem.

Thanks in advance
