Hello, Sometime our MPI application makes the gm driver write something like this: GM: LANAI[0]: port=2 bogus page SEND ptr = 0x40667020 FAILED (maxidx=32767) By take a quick look at gm source I understood that there was a send from a buffer allocated in non-dma-able memory causing the driver send fake data (0) from a special dma memory page. I think this was caused by the fact that the buffer was in swap instead of physical memory, correct me if I am wrong. Does --gm-can-register-memory option forces buffer to be in DMA-able memory?
