No, I thought you ran this yourself.

Then the answer from Gigabyte doesn't prove anything. You can also boot 
Linux without seeing this problem in most cases.

Your BIOS does not have the required erratum workaround. We will provide 
a patch to close that hole but since the problem is not easily 
reproducible (and the erratum is also not easy to trigger) it may be 
difficult to say whether it really helped with your problem.
