           Summary: Infinite loop printing "__find_get_block_slow() failed."
                    on accessing intentionally corrupted ext4 fs
           Product: File System
           Version: 2.5
     KernelVersion: 2.6.29-rc2 + the patches for #12430
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@kernel-bugs.osdl.org
        ReportedBy: sliedes@cc.hut.fi


Hardware Environment: qemu x86
Software Environment: Minimal Debian sid/unstable
Problem Description:

Accessing the attached intentionally corrupted ext4 filesystem causes a
seemingly infinite (at least _very_ long) loop where kernel floods dmesg with
these messages:

[   67.126302] __find_get_block_slow() failed. block=4294967296, b_blocknr=0
[   67.126609] b_state=0x00000020, b_size=1024
[   67.126798] device blocksize: 1024
[   67.126972] __find_get_block_slow() failed. block=4294967296, b_blocknr=0
[   67.127244] b_state=0x00000020, b_size=1024
[   67.127415] device blocksize: 1024
[   67.127573] __find_get_block_slow() failed. block=4294967296, b_blocknr=0
[   67.127844] b_state=0x00000020, b_size=1024
... ad infinitum

Steps to reproduce:

1. bunzip2 the attached filesystem image
2. mount hdb.153 /mnt -t ext4 -o loop,errors=continue
3. rm -rf /mnt >&/dev/null
