Mr. Christopher,
I tested with the latest upstream kernel 4.2-rc8 and the issue is reproducible even there. I tested 2 times - each time with the same result: suspend/resume attempt worked 3 times and then fourth attempt to suspend froze PC (screen went off, hdd stopped spinning, but PC fan and power led kept on, and the resume from this state was not possible, only hard reset).
