Jul 16 01:42:38 koboldx-x870e kernel: thunderbolt 0000:1c:00.0: probe with driver thunderbolt failed with error -110
This TDX error showed up after i updated from kernel 7.0 to 7.1 btw Jul 16 01:42:36 koboldx-x870e kernel: virt/tdx: TDX not supported by the host platform
No idea about the thunderbolt, but the other 3 are safe to ignore. Indeed the vtx one is since kernel 7 also on my install, but it is up and running so it is just a false warning it seems.
The certificate error is secure boot related, even if it is turned off.
