Hi all, Root cause is chinese Arduino board (ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter). The board sometimes works and sometimes doesn't on the same version of kernel. ========= y = works n = not works ========= I tested in next sequence: - 4.1 - n - 4.0 - n - 3.19 - n - 3.15 - n - 3.13 - y - 3.14 - y - 3.15 - y - 3.17 - y - 3.18 - y - 3.19 - y - 4.0 - y - 4.1 - y But on the next morning the board didn't work again with 4.1 kernel. Original Arduino board works perfect on any version of kernel. Thank in advance for the answer.
