It happens on all machines that I boot that kernel on, if that is what you mean.
As far as I can tell, the other /proc/sys/lnet entries are correctly populated.

ls /proc/sys/lnet/
catastrophe                  console_ratelimit  debug_path     printk
console_backoff              daemon_file        dump_kernel    subsystem_debug
console_max_delay_centisecs  debug              memused        upcall
console_min_delay_centisecs  debug_mb           panic_on_lbug


Cheers,

Guy
