I just got informed that this patch[1], as part of the current stable
queue-3.5 seems to break cryptsetup/ LUKS on a USB harddisk attached to
a sandybridge i5-2300 (USB 2.0). While I personally don't see a direct
relation, especially considering the other USB patches in queue-3.5,
bisecting the problem led to this patch - and reverting only this patch
from 3.5.2+queue-3.5 fixes the problem for the user.
