~22min
Status in gdm3 package in Ubuntu:
Confirmed
Status in linux package in Ubuntu:
Incomplete
Bug description:
UBUNTU 19.10 installed on ThunderX2 saber ARM64 machine. If the system
left idle for ~22min it becomes unresponsive. The system will not take
any inputs like from UART, ping ..etc. The system will completely
freeze and we need to hard reset the system. It could be possible the
system goes to hibernate state and could not able to come out of the
state.
