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?

A+
