Message:

VMM/IEM: Implemented generic fallback for misaligned x86 locking that is not compatible with the host. Using the existing split-lock solution with VINF_EM_EMULATE_SPLIT_LOCK from bugref:10052. We keep ignoring the 'lock' prefix in the recompiler for single CPU VMs (now also on amd64 hosts). bugref:10547
