Similar thing happens to me. Normally suspend and resume works perfectly, but once in a while it resumes alone just after suspend, and after that trying to suspend locks the machine hard. I do not know if it's a coincidence, but locks occurs only when I have the ethernet cable plugged in. Never happened with Linus vanilla kernels, but could be another coincidence too. Nothing special in dmesg or in logs.
