Hi, when migrating ancient machine to become KVM guest, I am facing a problem that KVM gives me the error below when being passed oldish vmlinuz image: === # qemu-kvm -kernel vmlinuz-2.4.33 KVM internal error.

The instructions around eip look reasonably valid from a quick look (this is monitor output from the time it crashes): === (qemu) x/5i $eip 0x00000000c027a841: movq (%esi),%mm0 0x00000000c027a844: movq 0x8(%esi),%mm1 0x00000000c027a848: movq 0x10(%esi),%mm2 0x00000000c027a84c: movq 0x18(%esi),%mm3 0x00000000c027a850: movq %mm0,(%edx) === Is there any issue with emulating MMX?
