FUJITSU Futro S920 keeps rebooting

[Handbag8977]

I have two FUJITSU Futro S920 and they both keep "rebooting" every 10 minutes or so when they are connected to the WAN and my LAN AP.

So every couple of minutes I lose my network connection and hear the boot-up tune of pfsense, but no shutdown tune. Which made me think the issue is hardware related.

So I have tried using two different network cards:

• Dell Intel PRO/1000 ET 4x 1GbE Quad Port Ethernet Server Controller PCIe x4 0HM9

• Intel PRO/1000 PT Quad Port Server Adapter EXPI9404PT

Both show up fine in pfsense but have the same result.

I can also not find any issues in the logs, but I have attached them anyway.

systemlogs.txt
osboot.txt

Sometimes after a reboot I get the following notification:

I would appreciate it of someone could point me in the right direction to troubleshoot this further. Thanks!

Do you see a crash report?

Does it crash if you don't fit an expansion card?

Nothing in those logs looks like a problem.

Is it stable running some other OS?
