4.9 KLDload error

[Jin Guojun [NCS]]

A KLD module ncs_time_ctl.ko compiled on both 4.8 and 4.9 hosts can be loaded
by kldload on any 4.8 machine. But neither .ko files can be loaded on a 4.9
machine.
The error is:

4.9 # kldload -v ./ncs_time_ctl.ko
kldload: can't load ./ncs_time_ctl.ko: Exec format error

kldload should give more error information on what function it failed to load.

Is this possible a 4.9 bug in kldload? or does some KLD mechanism has been
changed
in 4.9-RELEASE?
Is there any way to analyze what is wrong in the 4.9 LKD system?
