Anton Kanishchev, thank you for testing the mainline kernel. The next step would be to identify the last mainline kernel release that the problem is demonstrated in, followed consecutively in version by the first mainline kernel release that fixes this problem (reverse mainline kernel version bisect). Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
