            Bug ID: 89511
           Summary: USB-storage mount error
           Product: File System
           Version: 2.5
    Kernel Version: 3.2.63
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext4
          Assignee: fs_ext4@...nel-bugs.osdl.org
          Reporter: itou_jun@...oseek.jp
        Regression: No

When my USB-storage does mount, it becomes the error.
It occurs from ver.3.2.63 and does not occur in ver.3.2.62.
I ride below dmesg.
It reappears in this series of io data by all means.
I confirmed that hardware did not have a problem.
The following changed kernel in menu in the same environment and tested it.
Because a write is not done to become the read only, please help me.
Even ext3 format occurs.
I doubt file system.
Thank you.
