Literally 4.9-xxxx?  No 3rd number? And why 'xxxx'? (Hint - obfuscating doesn't
help here, it's hard to debug when we don't see the *actual* string.)

Some unames from my various machines:

4.15.0-rc7-next-20180112-dirty (x86_64 laptop)
4.9.35-v7+  (raspberry pi)
4.9.73   (Lede-based router)
3.10.0-229.20.1.el7.x86_64 (RHEL 7.3)
3.0.101-68-default (SLES 11.4)

I'm pretty sure the fact that your uname is only returning 2 numbers
before the '-' is the root cause of your problem.
