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
