You are likely not using the right set of target channel/slave
addresses, etc. if you are getting a timeout.  i.e. the messages are not
going to the right place so you're not getting a response.

Are you calling ipmi_sdr_oem_parse_intel_node_manager() at some point?
That should go in after the ipmi_sdr_ctx_create() and after you load
and/or create a SDR cache (e.g.
ipmi_sdr_cache_create/ipmi_sdr_cache_open).  Then afterwards you can
pass the values into
ipmi_cmd_oem_intel_node_manager_get_node_manager_statistics().

Feel free to respond if you're having more problems.
