(Solved) Unraid 6.11.1 Reboots - AMD Ryzen 9 3900X & Asrock Rack X470D4U

[Thecreativeone691]

I have a new unraid system which will always reboots when I got to the VMS page on the web interface, sometimes just going to the page will cause it, sometimes clicking the Add VM will cause it, sometimes Creating the VM will cause it but if I'm able to get to that point almost always booting the VM will cause it. Nothing special or passed thru as of yet just a simple windows VM (though not actually installed just boots to the bios). 

 

Dockers, Shares and everything else will work fine no issues there. I've ran Memtest 86 for over 52hrs with not a single error and ran some CPU Stress tests with AIDA64 as well with no issues. AMD Ryzen 9 3900X is on the latest Microcode.  

 

I've also re-imaged the USB stick using Unraid usb creator and just copied back the config directory to rule out any possible system file corruption. 

 

Done the random fixes I have seen for Ryzen with unraid, disable Global C States, disable Precision Boost Overdrive &  CPB and disable the Low power mode and use normal. 

 

I'm on the latest bios version but have tried several other versions as well all with the same issue. 

 

Setup Syslog as well as diagnostics neither log shows anything around the time of the crash where the server fully reboots. Anything I've see similar to this is from people pass-thru hardware or GPUs, but I don't have anything passed thru.

That's a strange one, disable IOMMU just to test if it makes any difference, you can still create VMs just not pass-through any PCIe devices.

Disabled IOMMU and still the same result. So far this one has me stumped.

It was my 2TB NVME Cache Drive, no errors no signs of failure but it died and isn't even detectable anymore now, removed it from the pool and it works great.
