I manage a server for a friend. This server ran fine but when I tried making it go to sleep at a specific time and wake up using a cronjob, the server would not wake up using rtcwake. While trying to fix this the server started to shut down after ~10 minutes every time he turned it back on.
I tried looking for a cause using sudo cat /var/log/syslog | grep -i "panic\|error\|hang" and sudo journalctl -b -1 -e but that didn't show anything strange. BIOS also doesn't have any power management setting turned on.
After giving up I decided to fully reinstall Ubuntu servers 22.04 however it still shutdown after some time. We think it shuts down faster when accessed using SSH but weren't able to fully verify it.
The server has the following components:
- i7 6700k
- 16GB DDR4
- NVIDIA Geforce GTX 660
- ASUS Z170 pro gaming
- 120 GB boot SSD
- 2 3TB Harddrives in RAID 1
Running kernel version: 5.15.0-47-generic
