I see.  My opinion is that in the long term, you're better off writing
a "native" QNX driver rather than trying to port a driver from another
OS, although I understand that sometimes short-term issues make doing
the right thing impossible.

No idea really.  Does the Linux mthca work on the same hardware?  If
so I guess you would have to figure out how the behavior of your
driver is different.  If you don't have Linux running on your platform
then you just need to debug the driver/hardware ... perhaps hardware
bus analysis would be helpful to understand what's happening.
