Hyper-threading was enabled in the BIOS and the Skylake processor looks 
good.

lscpu:
Thread(s) per core:    2
Model:                 94
Stepping:              3

But both of the "intel-microcode" and "amd64-microcode" packages were 
installed, so I removed amd64-microcode.

apt-cache depends amd64-microcode:
amd64-microcode
   Breaks: intel-microcode

Thanks!
