Thanks for the extra information. So I've seen something similar with INQUIRY EVPD=0x83 emulation using recent v3.7-rc2 code, but it looks like the same regression is effecting v3.6.x stable as well. I'm pretty sure this is regression related to the recent re-factoring of control CDB emulation logic, most likely that INQUIRY buffer allocations are no longer being explicitly zeroed with iscsi-target. Tracking down this item is currently on my short-term v3.7-rc TODO list, and I should have something for you in the next 24 hours.
