so, how is this related to your problem? What I'm trying to say, avoid such
ugly systems, if s-t-r does not work for you. Preferably, try to boot in the
text mode only, configure your network. Avoid any boot acpi_sleep parameters.
echo mem > /sys/power/state
After wake up, test whether your machine is still reachable over network. If
so, use ssh to connect to your laptop. Try vbetool post, you should see text
mode with cursor (try to hit enter, if you see nothing just blank screen).
If you succeed with this, s-t-r will work for you. If not, then there is a
problem with another piece of hardware and s-t-r. You may try to remove all
uneeded modules and try it again.
