Hello,
I have changed my configuration so that I have a 8 gigabyte large swap partition, and I have also made the changes you suggested to my hibernation/fill-tmpfs script so that a tmpfs other than /tmp is used.
Unfortunately, nothing changed. I still get hangs after a few lines are printed to the console. The last two lines are from your patch. Here is an observation from an actual test which ended with a hang:
=== 8< === PM: Preallocating image memory shrink_all_memory: start shrink_all_memory: req: 375019 reclaimed: 48055 free: 326810 === >8 ===
One thing I should note is that, before your commit, I never had any problems even though my swap size was not two times the size of my physical memory and even though I used tmpfs as /tmp.
If there is anything I can do to debug this problem please let me know.
Regards,
M. Vefa Bicakci
