So, you think it's a problem with fc36?

https://koji.fedoraproject.org/koji/buildinfo?buildID=1991182 shouldbe the
binary build in use, and looking at the debug syms, it reallydoes
have:ffff82d040439c80 <amd_iommu_init>:...ffff82d04043a00c: 0f 6e c2
movd %edx,%mm0ffff82d04043a00f: 0f 62 c0
punpckldq %mm0,%mm0ffff82d04043a012: 49 89 87 c0 00 00 00 mov
%rax,0xc0(%r15)ffff82d04043a019: 41 0f 7f 87 d0 00 00 movq
%mm0,0xd0(%r15)ffff82d04043a020: 00So hardware is correct - this build of
Xen is nonsense.The binary is also full of .annobin_ stuff which appears to be
some kindof GCC plugin for watermarking.Michael: Any idea what's going on here?
Something has caused GCC toemit some MMX logic which is ultimately why things
exploded, but thisprobably means that some of the build CFLAGS got
dropped.Thanks,~Andrew
