RE: System hangs on Debian 7.6 and 7.8 when enabling Cluster on die (COD) with Intel Haswell and Broadwell processors

Hi Holschuh,

I found if system install all of packages except laptop, the issue is disappeared.
So the issue is caused by laptop package.
Does anyone get this issue?

And make sure you're using up-to-date microcode.  COD is not the kind of thing that is safe to just enable bindly and hope for the best.
