Do you run the VF on the same system/kernel as the PF, or the VF is 
probed to VM which runs the latest kernel and the PF runsolder kernel 
(which?)

Can you also hook the PF code that serves this flow to see where we 
actually fail? basically, we should be going this way 
mlx4_ALLOC_RES_wrapper --> counter_alloc_res -- so I'd like to see which 
of the branches in counter_alloc_res fails...

Or.
