s2ram autowake regression is still there in 2.6.21-rc4-git

[Pavel Machek]

Hi!

Run this script. The s2ram at the end of it will wakeup immediately
after going to sleep, bad. I tried reproducing it with smaller
version, but was not too successful.

#!/bin/bash
killall klogd

echo -n "testing refrigerator (testproc)..."
echo testproc > /sys/power/disk
echo disk > /sys/power/state
echo "okay"

sleep 2
echo -n "testing drivers (test)..."
echo test > /sys/power/disk
echo disk > /sys/power/state
echo "okay"

sleep 2
echo -n "testing swsusp (reboot)..."
echo reboot > /sys/power/disk
echo disk > /sys/power/state
echo "okay"

sleep 2
echo -n "testing s2ram..."
s2ram
echo "okay"

sleep 2
echo -n "testing swsusp (shutdown)..."
echo shutdown > /sys/power/disk
echo disk > /sys/power/state
echo "okay"

sleep 2
echo -n "testing swsusp (platform)..."
echo platform > /sys/power/disk
echo disk > /sys/power/state
echo "okay"

sleep 2
echo -n "testing s2ram..."

...this is enough to trigger it. I've done my testing on x60, FWIW.
