System Immediately Reboots After Graceful Shutdown [ Supermicro X9DRL-iF, TrueNAS 13.0, E5-2630v2 x 2 ]

[officialnsa]

Hi there,

I've been experiencing this problem with my machine since I built it and installed TrueNAS. Whenever I shut down the system, no matter which way I do it, it always turns itself back on immediately. I have tried shutdown -p now, ipmitool power soft, the web GUI shutdown button, all to no avail. The only thing that worked for me was ipmitool power off, however I believe this isn't ideal as it's a fairly abrupt stop for the system. I've posted the contents of my /var/log/messages, around the time of my most recent (unsuccessful) shutdown:

As in the title, my motherboard is a SuperMicro X9DRL-iF. I have fairly exhaustively scanned for BIOS settings that seem pertinent—AC Power Off behavior (set to stay off), turned off Watch Dog, even messed with ACPI settings (changed Sleep State from S1 to Suspend; let me know if that's a bad idea). Any help would be appreciated—I certainly don't want to have to resort to forcible power-downs every time I need to power off my machine.

I'm fairly new to servers, especially server hardware, but I'm a C developer + relatively experienced with sh/bash so don't be shy if you feel the need to give complicated advice. I'm unfamiliar with all the ins and outs of how these systems are usually set up, but I can follow directions well.

Thank you very much for any help you can offer!
