[openib-general] How to debug QP INIT->RTR -22 error

[Steve Wooding]

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.
