Hi Mao, I see...the partner is not using a regular Ubuntu build. This patch was introduced upstream in kernel 4.17, so it's not present in a regular 4.15 or 4.16. It is present in our Ubuntu kernel though, because it was backported and added, but I can't guarantee it's present in the custom kernels the partner is using.
Some alternatives for us to resolve this issue: a) If I could access the source tree of the partner kernel, I can check and even add myself the patch in case it's not there; b) The partner could test Ubuntu official kernel 4.15.0-34; c) The partner could test upstream kernel 4.17 (or 4.18). Preference is alternative (b), but (c) is ok too. The first alternative is the least preferred.
