We're getting further, but no cigar yet!

This appears to be this line:
/* "monitor %eax,%ecx,%edx;" */
asm volatile(
c010121d: 31 c9 xor %ecx,%ecx
c010121f: 89 f8 mov %edi,%eax
c0101221: 89 ca mov %ecx,%edx
c0101223: 0f 01 c8 monitor %eax,%ecx,%edx
My *host* CPU certainly claims to have 'PNI', and thus I suspect 'monitor'.
I'll try to get this skipped so I can continue testing. Let me know if there
is anything I can do to help!
