means that iser got local protection error (=4) on the first buffer we
used with IB (the connection handshake buffers belong to the IB CM,
not to the ULP) which is the login request. Sounds like something is
broken maybe dma mapping wise, for this reason I think its likely that
the problem might not hit me on my testbed [...]
okay, I've tried 3.0.15 with your .config slightly changed for my local
SATA disk, will send you copy of my .config , and, iser works for me...
so you need to try a bit harder and send me your logs... I'm using
iscsi-initiator-utils-6.2.0.872-21.el6.x86_64
Or.
My board ID is MT_0D81120009 which is a bit different but the HCA is
ConnectX b0 as yours, I'm using non GA firmware, but I find it hard to
believe this is the reason for your failure
