This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- artful' to 'verification-done-artful'. If the problem still exists, change the tag

That would indicate the fix is in from v4.15-rc2 -> 4.15 Final. I'll review the commits in that range, but there are probably thousands of them. It will help to narrow it down further. Could you test the 4.15 release candidates on the following page to find the last good kernel and first bad
