Thank you. In my case, I have the same block/allow but the primary does an explicit probe of a DMA engine on the processor, the secondary is notified and it crashes. It should not crash I suppose. The same software is running on several machines (100) but the problem is sporadic just on two of them.
Very strange. Thx, Antonio.
