Thanks Michael,
Just looking at the kernel-space code gives me a few things to check
with my app.
Cheers,
Steve.

Subject: How to debug QP INIT->RTR -22 error
Hi there,
I'm trying to make a QP connection using the CM, but the active side
cannot get to the RTR state. ibv_modify_qp returns errorno -22, invalid
argument.
What would the best way to find out exactly what the error is and help
me fix my app (just to say, it is only my app that's broken, nothing
else)? Would turning kernel debugging on be helpful at all?
Thanks everyone,
Steve.
Yes, enabling debug messages in mthca is typically helpful.
The relevant code with tests is in mthca_qp.c, function mthca_modify_qp,
and in uverbs_cmd.c, ib_uverbs_modify_qp.
