Actually since you have mentioned - I have checked my x60 - same problem
- only one CPU. However I was running 4.8.13 with uptime 33 days,
multiple sleep/wake-ups.
Installed a current EOL 4.8.17 and rebooted - I see 2 CPUs. So the issue
is older then 4.10 kernel, and I suspect it is the CPU hotplug / wakeup
related...
