Comment(by Quozl):

 Reproduced.

 Excluded fs-update.  Excluded external SD port.

 ----

 A text file and a .zd file were placed on ext4 formatted external SD card,
 and on an ext4 formatted USB drive, and OpenFirmware was used to read them
 into a 0xff filled buffer.  The .zd file contained this byte sequence as
 first line: "zblocks: 20000 7331", hex:

 {{{
 7a 62 6c 6f 63 6b 73 3a 20 32 30 30 30 30 20 37 33 33 31 0a
 }}}

 The buffer contained this byte sequence after read:
 {{{
 7a 14 58 96 fa 75 0b 72 7a 1c ee 3a 73 1a 40 dc 71 d4 b0 a4
 }}}

 Displaying the text file with ''more'' showed no useful output.
