Which version of gcc did you compile OVMF with?
I can reproduce with a "Page-Fault" in the same modules, but with an OVMF
binary compiled later, I have a "General Protection" fault in the module
PcRtc...
I blame -flto of gcc.
If you have gcc 6.3, to build ovmf without -flto, either:
- build using OvmfPkg/build.sh -a X64 -n 4 -t GCC49
(that is "-t GCC49" added to ./build.sh call)
- or edit OvmfPkg/build.sh, replace GCC5 by GCC49.
I can try to find out what is wrong, and report it upstream.
