Hi Unraiders,

 

so I just pulled the trigger of a new system b450 msi tomahawk max + ryzen 3900 + cosair 32gb 3600mhz c18. 

 

Once I followed the proper tutorial to unstub the hardware passthrough, the new server boots up like a champ with all 12 glory cores. All docker works fine, when I start a VM though, it just crashes and unraid goes with it. after unraid reboots, the vm manager even disables vm.

 

I researched a couple topic in the forum and followed these toturials:

 

flash storage config edit: 

kernel /bzimage
append pcie_no_flr=1022:149c,1022:1487 vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot

 

disabled WSD

 

unstubbed everything,

 

updated to latest bios

 

disable PCIe ACS override

 

starting VM from scratch using just vnc,

 

downclock memory

 

none of them worked... and it just keeps crashing. Attaching syslog

 

a couple noteable errors:

 

Nov 22 12:02:53 Tower kernel: mce: [Hardware Error]: Machine check events logged

Nov 22 12:02:56 Tower ntpd[2189]: kernel reports TIME_ERROR: 0x41: Clock Unsynchronized

 

any tips on what I can do next to troubleshoot?

 Thanks, disabled a bunch of bios settings and downclocked to 3200mhz, seems stable for now, will monitor for a couple days.

 

I think one that I have disabled might have been the culprit, the resizable BAR support, I read somewhere else that unraid doesn't support this.
