Not sure if you saw my latest response, this was resolved by switching 
from blktap2 to phy (first time using iscsi, usually use disk images). 
Probably not desired behavior still though. Blktap2 seemed to work fine, 
with the exception of the hang on shutdown. (Performance benchmarks seem 
to indicate phy and blktap2 are equal as well)
