in my setup that doesn't produce any output...if I do this:

[root at alekhine mthca0]# cat /sys/class/infiniband/mthca0/board_id

that's an empty output. however cat'ing other files give some stuff e.g.:

[root at alekhine mthca0]# cat /sys/class/infiniband/mthca0/fw_ver
4.6.0
==============================

[root at alekhine mthca0]# cat /sys/class/infiniband/mthca0/hca_type
MT25208 (MT23108 compat mode)
==========================================

[root at alekhine mthca0]# cat /sys/class/infiniband/mthca0/hw_rev
a0
==========================================

thanks, som.
