@Matt Taylor I have not filed an upstream bug for this. Until now I was not sure if I am the only one having this bug, so this information is helpful for me at least. As you can see in the activity log, I followed the procedure suggested in the Ubuntu Wiki, however, this did not result in more information. I also tried to remove as many kernel modules as possible, but I was still not able to resume. I even connected a serial console to my PC to see if some information is printed while supending/resuming, but the console is switched off before the freeze. Maybe there is more debug instrumentation in the kernel which could be activated or we have to modify the kernel with printk statements or use kgdb to find the place where it is freezing or the difference between the states after hibernation and power-up.
