Dear All,

I have a new hardware I ordered, and it used to work alright until couple of days ago, when the machine didn't boot. I assume, a driver got auto-updated. I am unable to boot proxmox without disabling the apci (e.g. kernel mode apci=off); and when I do that Linux doesn't see the additional cores (e.g. /proc/cpuinfo - shows only one CPU/thread).

Any guidance how the problem can be resolved?

thank you
