unRAID constantly crashing

[Cliff]

I am running unraid that runs a Widows 11 VM that have been running well for over a year. But after upgrading to 6.10.0-rc2 I think my Windows11 vm is making my unraid-server crash several times a week. I am passing through a nvidia 1060 to the VM and this have worked for a long time before upgrading.

 

 

 

But now suddenly I see the log is at 100% and is filling up with:

 

 

 

`021-12-11T22:59:01.176974Z qemu-system-x86_64: vfio_region_write(0000:0a:00.0:region1+0x172ea8, 0x0,1) failed: Device or resource busy`

 

 

 

Or the server suddenly just reboots

 

 

 

Does anyone know how to fix this ?

I was having a similar problem that turned out to be failing power supply. It tested OK but as soon as I put a new one in the problem went away!

Usually this is caused because the gpu is in use by the host itself and that memory regions can't be write by the guest.

See what is using that region, use terminal command: cat /proc/iomem

Probably efifb is using that regions, if this is the case add video=efifb:off to your syslinux config.

I don't really know what to do. I have tried booting up windows directly from my nvme drive and it runs fine for several days without any reboots/crashes. I have also tried running memtest from 12 hours and also stress testing the cpu/gpu for a couple of hours without problems. But as soon as I launch unraid from USB the system reboots withing 20 minutes even after disabling vm-engine and most of the dockers.

 

I even tried copying the config-folder from the usb and reformating the usb with unraid-config tool then copying back the config folder. But system still reboots after a while.
