I've an issue with the iSCSI target (not COMSTAR) in b107. When I apply a
TargetPortGroupTag restriction to a target iscsitgtd core dumps. Remove the
tpgt from the iSCSI target and the initiator can successfully connect. For
testing I'm not using any ACLs or CHAP though I have applied these and it made
no difference. Has anyone else encountered this?

I can provide snoop capture of the session thought there is nothing to see
other than the absence of a response to the client's SendTargets=All request.
