It looks like this address even gets executed earlier: qemu-system-x86-12024 [002] 278153.809990: kvm_emulate_insn: 0:9315:ea 1a 93 00 00 (real) qemu-system-x86-12024 [002] 278153.809991: kvm_entry: vcpu 0 qemu-system-x86-12024 [002] 278153.809992: kvm_emulate_insn: 0:931a:31 c0 (real) I guess it's a jump to 931a. Puzzling that later it becomes a jump to self. -- Andriy Gapon
