CPU stuck at 100% on VM proxmox 8.3 latest kernel

[andrei indreies]

Hello everyone,

I have a big issue with my proxmox env:
my device:
cpu: ryzen 5 4650g pro
ram: micron 32GB ECC unregistered
motherboard: B550m ds3h
hdd: currently only 1x 16TB exos x16 and 1x500gb

Passthrough to truenas core vm.

After a while my cpu goes 100% on my truenas core vm and is totally unresponsive till force stop and reboot.

What can I do? I read that was because of the kernel 6.1 but running on the latest one 6.8.12-4
it is not because of the vm because the avg usage of the cpu is under 1% and without any interaction or scheduled tasks my vm cpu goes crazy up to 100% once every few hours. This is actually killing me.

my vm conf:
