What version of open-iscsi and what is the ping timeout?

Could you try the kernel modules and tools from 
http://www.open-iscsi.org/bits/open-iscsi-2.0-871.tar.gz.  I did a tiny 
change to the ping code, and it looks like for some other group it has 
fixed their problem (at least I have not heard back from them in a 
couple of weeks).
