Kernel hang when using script

Module compiles and installs fine.
When manually adding devices + button assignment it works a treat however, If I use a script including the provided x3 script it causes a kernel soft hang.

Kernel 4.9
TM warthog

I've attached a log.

Just to update though this appears to be abandoned, Working fine on Antergos with the 4.10 kernel

I can now use my warthog for freespace and X3

Weird. It hangs if I add too quickly, but it works if I add a "sleep 2" between add_button's...
Also, I can't seem to find the "new" jsX it would create. I am using 3 devices.
