[Machine Check Event while running VM]

Hi! My Unraid server hard resets randomly while in any of my VMs, it happens very infrequently, but has been a huge pain to diagnose. I haven't been able to find a common denominator for this happening, but on reboot Fix Common Problems logs an MCE. I have attached my diagnostics below. Any advice would be hugely appreciated!

Thank you for all your support, and everything you do for the Unraid community!

 

I have gone ahead and opened an issue on the GitHub.

 

Take care.

Can you try to not bind the card to VFIO?

 

That has not done the trick either. Still no reset.

Can you try to boot Unraid with Legacy (CSM) mode instead of UEFI?

 

Thank you for the quick reply! Sorry I could not test until today I had a parity check running.

 

Unfortunately, that change has not seemed to help... I still get the same error in the VM logs:

 

qemu-system-x86_64: vfio: Cannot reset device 0000:0b:00.1, no available reset mechanism

I have been trying to get the AMD Vendor Reset plugin to work for quite some time and have not found any success so far. My goal is to just be able to cleanly start and stop a Windows 11 VM. I have a 5900X and a Radeon VII, running Unraid 6.10.3. I have attached my diagnostics below. Any help or guidance would be greatly appreciated!
