Oh my,
didn't notice this platform specific issue.
I pick this system because it's a laptop with SSD, and modules are easy to

I think I will need to retest this, please ignore the test result.
Thanks

Thanks for testing and sorry for the slow reply.
But did you test with a machine affected by the bug? I'm asking because
you seem to have been testing an Ivy Bridge machine, and the bug is
reported for an Haswell-ULT platform. So far I've only heard of Haswell
and Broadwell being affected by this.
