One simple and quick check
Do you specify ATOMIC_ACCESS when you open the QP ?
yes - IB_AC_ATOMIC | IB_AC_RDMA_READ | IB_AC_RDMA_WRITE |
IB_AC_LOCAL_WRITE are all set on the QP.

what HW do you use? InfiniHost MT25208 - mthca.sys from
openib-windows svn.849, x64 on WinSvr 2003 (SP2); local process with RC
connection to another local process; should work?
if its mellanox HW there should be vendor syndrome in the EQE
entry , it should be in the same offset of the vendor syndrome of the
CQE.
You can change the driver to report it - this will might help us
to identify the problem
Thanks for the tip, will instrument the driver to display
information and get back to you.

IB_AE_WQ_REQ_ERR?
Hello all,
I'm working on DAT v2 extensions which include an Atomic
Compare-n-swap operation.
The comp-n-swap operation generates an async QP error callback
with
IB_AE_WR_REQ_ERR?
The IB_AE_WR_REQ_ERR code is defined as 'an Opcode violation @
the
responder'?
Any clues as to what might generate an IB_AE_WR_REQ_ERR or what
an
opcode violation @ responder implies?
Anyone have an IBAL based compare-n-swap test program they would
like to
share?
Thanks,
Stan.
