Thanks for the update. We can perform a "Reverse" bisect to identify the commit that fixes this bug in mainline. We would first need to identify the last kernel version that had the bug and the first version that did not have the bug. We now know that v4.15-rc7 is fixed. Can you next test v4.15-rc1?
