Can you see if the bug happens with and of these mainline kernels? We can perform a kernel bisect if we can narrow down to the last good kernel version and first bad one:
v4.14 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/ v4.15-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc1/ v4.15-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc4/ v4.15 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15/ You don't have to test every kernel, just up until the kernel that first has this bug.
