Help! add-ons driver won't be loaded

Development OS

Hi,I’d like to try to fix problems on system driver(idualwifi7260).
So,I got source codes,added debug codes, and built it.
Then, I tested my test-driver but it’s not loaded.
Syslog said,just only “General system error”.

KERN: Could not loadKERN: kernel add-on “/boot/system/non-packaged/add-ons/kernel/drivers/dev/net/idualwifi7260”: General system error

I have no idea to investigate what’s wrong with me.
Anybody knows how to investigate the cause?
Or how to solve this problem?
Thanks in advance.
