If the patch is really guilty, then it's probably best to revert it
before 4.10 gets released, but...

I'm not 100% convinced that 4.9 is fully stable and that the patch
is the reason for the crashes you see.
What kind of crashes do you see? Userspace or kernel ?
I know we still face random userspace crashes which happen with plain kernel 4.9/stable too.
Dave is still trying various patches to resolve those crashes.
