Hello. According to AMD docs both FXSAVE and FXRSTOR instuctions have to generate GPF if the memory operand is not aligned on a 16-byte boundary. Qemu in contrary does not generate such exception in this case.
Unfortunatelly, I'm not able to write proper patch since I have no experience in hacking qemu code (it has to be most likely fixed in the target-i386/translate.c file, around lines 6210-6237). regards, M. -- Michal Schulz
