I changed SLEEP_MODULE="uswsusp" to "kernel" in
/usr/lib/pm-utils/defaults and tested your patch mentioned above with
linux 3.2.9.
Unfortunately the behaviour didn't change at all - I can see the same
problems as before.
I tested with and without X. I tested with the call "pm-hibernate" and
with "echo disk > /sys/power/state". I always could see the corrupted
files after 2 to 4 times of hibernating / resuming.
Kind regards,
Andreas
