To mitigate meltdown vulnerability updated kernel to 3.13.0-139-generic #188-Ubuntu. Approximately one hour after system boots I get this bug. I can`t access server via IKVM(ssh works fine). Also I got problem with server reboot. On "reboot" or "init 6" commands server halts. Only option is to reset server via IPMI. After server reseted and system boots, IKVM and reboot works as intended for approximately one hour.
