Hi,
Somebody in the list suggested we could test S3 with a kernel which
doesn't touch any device. Considering there are many broken drivers
(especially hard disk driver in some systems), this sounds like a good
method to narrow down S3 bugs. For those who want to try it, you can
make a kernel without any driver support, and make attached file as your
initrd, and see if S3 works. The attached initramfs doesn't touch any
device and just does something like below:

echo 'mem' >/sys/power/state
echo xxxxxxxx
while true; do done


Thanks,
Shaohua
