Ah, OK.  Thanks!

Same that I've been running all along...  This is RHEL 5.2 w/ OFED 1.3  
built on top of it.  I know it comes bundled, but it did not work.  I  
am using whichever Open iSCSI comes bundled w/ OFED 1.3.   Also, I  
remember I had to update the tcl pkg for some reason?  Other than  
that, stock kernel and libraries.

No, I don't think related to that.

Oh, OK.  This is very helpful.  I'll explore from this side (I was  
thinking it had to do w/ some iSCSI parameter, but maybe I'm just  
blowing up the RC channel for no good reason).
