Please see my reply to Bjorn, the resume is just 60+ seconds delayed, not completely failing, I was wrong about that. I attached my logs there. To respond to your question, I applied 7b3ba09febf4 on top of fe15c26ee26e (which is the parent of e8b908146d44) and tested that. Hopefully I understood the instructions correctly. That kernel resumes just fine, with the expected speed (~5 seconds), no extra delay. (If there's a speed-up, I can't really tell). Thank you for looking into this. Kamil Páral
