I finally found it. A r237477 memstick boots fine. A r237478 memstick does not.

237478 is the following commit by mav@:

------------------------------------------------------------------------
r237478 | mav | 2012-06-23 14:32:53 +0200 (Sat, 23 Jun 2012) | 3 lines

Add scsi_extract_sense_ccb() -- wrapper around scsi_extract_sense_len().
It allows to remove number of duplicate checks from several places.
