  1.

  2. The system runs automated tests (using Robot Framework, python tool), interacts via CAN bus (using Intrepid ValueCAN3) with system under test, does some unheavy networking. This was not happening on kernel 4.13.15, but started to happen on 4.19.50. I've separate issue on Github for Intrepid as their driver gives a call stack during boot up. However, not sure if this is related.
  3. At 19:54:55 kernel crash happens. That for some reason forces system to change time to Aug 24 1978. systemd reacts to that situation strangely, which puts system under unresponsive state, like infinite loop, potentially causing 100% cpu occupation (this is guess now) The printouts "Aug 24 07:45:10 ptc_lab_collab3_node17 systemd[20635]: Time has been changed" follows many times per second until node is rebooted manually.
