Hi,
Thanks for your suggestions. Your guess is right with the debugging
statement. Output is at the end.

Did these warning messages about INIT_IB not show up in the kernel
before you enabled CONFIG_INFINIBAND_MTHCA_DEBUG? They are printed
using mthca_warn(), which should be printed no matter what.
In any case I guess you built your firmware image without support for
1X. Is this right?
Do you have any theory as to why the drivers worked in 64-bit mode and
failed in 32-bit mode? I don't see any reason why the parameters
passed to INIT_IB would be any different.
Anyway, can you apply the debugging patch below and send the output
you get during device initialization (with
CONFIG_INFINIBAND_MTHCA_DEBUG
enabled, of course)? I'm guessing you'll see something like:
ib_mthca 0000:02:00.0: Max port width: 2
If my guess is correct, then we can use that value to get the correct
width to pass back to INIT_IB.
Thanks,
Roland
