Same problem. This time it is not stuck, but it was before. systemd-journald is using alot of cpu because of it.

Linux bpi-iot-ros-ai 3.10.107-BPI-M2U-Kernel #1 SMP Thu Aug 24 08:01:24 CST 2017 armv7l armv7l armv7l GNU/Linux

Does anyone know if this problem is fixed in kernel version 3.10.108? or what the problem is? I disabled and masked the journald service but thats not really a solution…
