Welcome @stetessi
Much thanks for post!

@stetessi

This is the orginal BIOS with corrects parameters for Qubes

If know, what are current “corrects parameters” for D16? Is spec-ctrl=no-ibpb-entry seen in No Qubes/VMs starting - libxenlight failed to create new-domain in 4.2.1 · Issue #9150 · QubesOS/qubes-issues · GitHub workaround? If test “family 15th CPU” please please post findings.

@renehoj

The KGPE-16 is not supported any longer, the CPUs are not compatible with recent CPU security patches.

https://github.com/QubesOS/qubes-issues/issues/9150
The comments in that thread has more details.

Hi again @renehoj always appreciate you share knowledge. When KGPE-16 become unsupported by Qubes are we back to "AMD appears to lack sufficient testing...and may harbor latent bugs" - Trail of Bits SecureDrop Workstation Review

Echo:

@stetessi

“This is a really unfortunate situation as the KGPE-D16 is the most powerful, binary blob free (when used with Libreboot, old Coreboot, or Dasharo) system that supports Qubes.”

@stetessi

If not have you another mother board to recommand ?
the issue is only affecting Xen, so if someone want to use this board with an other os there is no security problem ?

Very sad Know no answer

Any other BMC hardware removable or absent Qubes compatible boards still available? Anyone?
