Hello Eli,

Yes, this particular issue has been solved. However, I do see some other issues.

I seeing some new messages (not seen previously) in dmesg relating to 
ib_cq_destroy() (on ehca):

ib0: ib_cq_destroy failed
ib_destroy_srq failed: -16
ib_dealloc_pd failed

This happens after some network tests and an rmmod of ib_ehca.

At this point my guess is that this has to do with the split CQ patch. I have not 
had enough cycles to state that with absolute certainty. Can you please take a look too?
