At best someone who own the hardware and can test, so the reporter would be the
best option.  Most likely the upstream devs will ask testing the latest
development version or some patch, so we should be in Cc, of course.

Yes, we need to test with the latest upstream version before reporting to
upstream, at least.
4.17-rc kernel is found in OBS Kernel:HEAD repo, and 4.16.x is in OBS
Kernel:stable repo.

I *guess* the problem remains, but if these version work, there is another hope
for a quicker fix.
