Hello,

I've recently upgraded from kernel 4.12.12 to 4.14.13. Everything was fine on 4.12. Now on 4.14, my system sometimes freezes right after waking up from suspend. Facts:

- Happens roughly on every 3rd wakeup
- Affects both suspend and hibernate wakeups
- System sometimes manages to display the last picture that was visible before suspended
- No kernel log of wakeup is written
- System almost completely frozen, does not respond to anything EXCEPT for SysRq+b (reboot)

This is on a Lenovo Thinkpad W530.

Any idea how I would even start to diagnose this, seeing as there are no logs?
