Please apply commit d81cadbe1642 ("KVM: SVM: Disable AVIC on SNP-enabled 
system without HvInUseWrAllowed feature") to the stable v6.12 tree. This 
patch prevents a kernel BUG by disabling AVIC on systems without 
suitable support for AVIC to work when SEV-SNP support is enabled in the 
host.

Thanks,
Naveen

We need an ack from the KVM maintainers before we can take this.
