  There are worrying reports of filesystem corruption on ext4 in karmic.
  Scott says:
  
  12:36 < Keybuk> this whole ext4 thing is worrying me
  12:36 < Keybuk> I just downloaded an iso image, md5sum didn't match
  12:36 < Keybuk> downloaded it into an ext3 partition, matched just fine
  12:59 < Keybuk> and I know mvo has seen bugs with corrupted .debs in /var/cache/apt/archives
  12:59 < Keybuk> which seems to imply its any file large enough to use lots of extents
  
  I'm opening this bug report so that this bug gets tracked & triaged for
  karmic.  If we're unable to isolate the issue, we should consider
  rolling back to ext3 as the default filesystem in the installer.
