Alright... That's clear and thanks for helping me analyse, very new to the whole XCP-ng environment (and Linux in general)

/var/crash does not have anything in the folder

What I mean by lock up, is that it indeed stops responding to anything.
No more SSH, router doesn't show system in devices anymore, none of the VMs respond, no display on the screen attached to the machine, no input recognised from the keyboard.
The Power LED is still on and the fans are whirring so the machine stays powered on in any case.

I'll check in the BIOS for the C-states at least, the BIOS firmware itself is the latest version so if that doesn't help I guess I'm out of luck for now...

Hi all,

My XCP-ng server has the tendency to lock up every 1 to 3 days, with no visible clue as to why this is happening.
Memtest is passing with flying colours, so I can rule that out already.

From all logs I've checked the last message was in daemon.log, but nothing critical there. Timestamp was Sep 23 17:23:09 so I know the server was still on at that point.

The server has the following configuration:

• CPU: AMD RYZEN 9 3900XT
• MOBO: Gigabyte AORUS X570 ELITE
• RAM: HyperX 128 GB DDR4-3600 Non-ECC
• GPU: Nvidia GTX1060 6GB
• SSD: Samsung 980 PRO 1TB NVMe
• HBA: LSI 9400-16i

I have added both the GPU & the HBA as PCIe passthrough devices:

• the HBA to a VM running TrueNAS Core
• the GPU to a VM running Plex

Is it possible that because the CPU does not have integrated graphics that the PCIe passthrough to the VM is giving me issues, since the XCP-ng host then doesn't have a graphical output anymore?

I've added the report from the latest xen-bugtool execution here: https://drive.google.com/file/d/1DZ7etZp4viTSXecEn7Y1MeV_9-NKjvOK/view?usp=sharing
