pmgp: actually, this patch has been introduced between 17.01.1 and 17.01.2, so it's possibly the source of the issue rather than the fix.
The commit in question for lede-17.01 https://git.lede-project.org/?p=source.git;a=commit;h=820a39687db3b14c3264ee37548e2cac3f911bca

Could you test reverting these commits in the lede-17.01 branch (one at a time) and see which one introduces the issue?
