           Summary: ext4: delayed block allocation failed and application
                    not respond any more
           Product: File System
           Version: 2.5
    Kernel Version: 2.6.35.1
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@...nel-bugs.osdl.org
        ReportedBy: andrej.gelenberg@....edu
        Regression: No

dmesg:

EXT4-fs (dm-6): warning: mounting fs with errors, running e2fsck is recommended
EXT4-fs (dm-6): recovery complete
EXT4-fs (dm-6): mounted filesystem with ordered data mode. Opts: acl,commit=100
EXT4-fs (dm-6): mounted filesystem with ordered data mode. Opts: acl,commit=100
...
EXT4-fs error (device dm-6): ext4_ext_search_left: inode #3510: (comm
flush-254:6) ix (42117) != EXT_FIRST_INDEX (0) (depth 1)!
EXT4-fs (dm-6): delayed block allocation failed for inode 3510 at logical
offset 42117 with max blocks 77 with error -5
This should not happen!!  Data will be lost

transmission-daemon (which had the data on dm-6) don't respond anymore and i
can't kill it with kill -9. I can't shutdown the system too (only mit sys-rq
keys).
