That was right. I just did the test:
I used
stress -d 5 --hdd-bytes 100M -i 5 -c 5
to test.
In both cases, I:
1) booted to init S on an amd64 laptop with 1GB ram
2) for swsusp, swapoff'd /dev/hda1 and for suspend2 did echo 1 > /proc/suspend2/freezer_test
3) started stress
4) then started the attempts at suspending without restarting stress between each iteration.
I usually left a couple of seconds between each iteration to allow stress to fill buffers etc again, but
was called away once during swsusp testing, leaving a much bigger period between 2 tests.
Kernel log output follows (sorry about the long lines):
