Hi all,
After updating proxmox from version 7 to 8, I noticed a kernel oops on startup. Also the system becomes unresponsive after some time, even through the ipmi interface (though it seems to react correctly to a reboot).
Reverting to the previous kernel (5.5 instead of 6.5) removes the oops
This is a threadripper 3970X cpu on a Asrockrack TRX40D8-2N2T motherboard
