We definitely need more info here.  Why are you confident that the two
problems are the same bug?

Have you tested with mem-free Arbel, and does the problem occur there
too?  Or have you only tested Sinai?  Does the problem go away if you
remove the MTHCA_FLAG_SINAI_OPT flag from the mthca_hca_table[] entry
in mthca_main.c?
