Thanks, this is something worth investigating. What would be the exact
syntax to use to turn off pml_ob1_use_early_completion? Do you think the
same problem can also happen in the 1.1(.2) release, which is the one I
have also tested, since it comes with Ofed 1.2.5? Would it be worth to
try the 1.3? So far I have avoided it since it is tagged as "prerelease".

Thanks,
Biagio
