Hi all,

We put our servers in maintenance mode to update Proxmox, and iDrac / bios from our Dell Poweredge R630.

And, since this updates, Proxmox see only 1 core on our processor...

The normal number of core:

I try to boot on old kernel (5.15 instead 6.2), but same issue...

In the bios configuration, Intel VT is enable, and all core are enable.

Any idea ?

Thx !
