           Summary: kernel BUG at fs/ext4/mballoc.c:3141
           Product: File System
           Version: 2.5
    Kernel Version: 2.6.37
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@...nel-bugs.osdl.org
        ReportedBy: etele_@...email.hu

The Linux system that I'm running made a stack trace in the logs, and I was
unable to access the file system where the stack trace happened.
I could only reboot the system with "reboot -f -n" options.
