I think I have the same issue, but maybe not? I can't keep a pfsense or opnsense VM running for more than a day or few to save my life, I always see the CPU jump to 50% (I give it two cores) and it stays unresponsive until I manually restart the VM. There's no kernel panic or anything in the logs that I can find at all. I started with a vnopn box with a J4125 cpu, ended up replacing ram, and m.2 drive, then got a Protectli VP2420 with a J6412 cpu with new ram new storage, same issue is following me around like a ghost, still can't keep a pfsense or an opnsense VM running more than a day without a freeze/lockup of the VM. The host (proxmox) never crashes or panics. I'm so incredibly frustrated by this. I can't even use the watchdog to kick it in the pants when this happens because there is no watchdog driver under freebsd for the virtual watchdog hardware. My microcode is x17 which hasn't been updated by intel since July 2022 so I don't think it's that? I'm close to giving up on this and don't know what else to try aside from running pfsense on baremetal and giving up my desire to virtualize it. I've tried all that I can think to do, and then some. Yet no one else seems to be having this problem with Elkhart Lake's and Gemini Lake's are not affected? It's only Jasper's?
