    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
