1.Is this really a failure? Yes 2.Is it reproducible? If not, how often would it be reproducible? No really, about 1/3 resume will fail, especially when the image is large.
*IMPORTANT*: the resume more likely to fail when the image is large. 3.Did it work before on a prior kernel in the same release, or prior release? Yes, Ubuntu 14.04.3 with 3.16.0-40-generic #54~14.04.1-Ubuntu SMP Wed Jun 10 17:30:45 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux works well. 4.Do the symptoms vary at all between hibernation attempts? For example, one time WiFi didn't work, but another a kernel error shows on the screen. No, every time is the same. 5.Do you end up with a flashing Caps Lock light? No, totally hang 6.Please advise on how the computer hibernated, and resumed specifically.
