Sometimes mkfs.reiserfs from progsreiserfs-0.3.0.3-alt0.4 can create a
filesystem on which reiserfsck detects corruption (vpf-10640: The on-disk and
the correct bitmaps differs). Apparently working with such filesystem can lead
to hangs with kernel messages like:

vs-3050: wait_buffer_until_released: nobody releases buffer (dev 03:47, size
4096, blocknr 4325376, cou
nt 3, list 0, state 0x10019, page c18b5740, (UPTODATE, CLEAN, UNLOCKED)). Still
waiting (-270000000)  JDIRTY !JWAIT

Steps to Reproduce:
$ dd if=/dev/zero of=image.bin bs=1k count=1 seek=50588652
1+0 records in
1+0 records out
$ /sbin/mkfs.reiserfs image.bin
Warning: Device image.bin isn't a block device.
All data on image.bin will be lost. Do you realy want to create reiserfs 3.6 (y/n) y

  *************************************************************
  ** If you are using the latest reiserfsprogs and  it fails **
  ** please  email bug reports to reiserfs-list@namesys.com, **
  ** providing  as  much  information  as  possible --  your **
  ** hardware,  kernel,  patches,  settings,  all  reiserfsk **
  ** messages  (including version),  the reiserfsck logfile, **
  ** check  the  syslog file  for  any  related information. **
  ** If you would like advice on using this program, support **

Will read-only check consistency of the filesystem on image.bin
Will put log info to 'stdout'
