Dear Zhang, and other people.

Zhang, you mentioned that you thought that my notebook could resume if the BIOS is skipped, right?
Setting
# echo 1 > /sys/power/pm_trace
I tested all the variations of:
# echo ??? > /sys/power/pm_test # echo mem > /sys/power/state
that could be put into /sys/power/pm_test, but the notebook always "resumed" ("woke up" from "sleep").
On the other hand, if I do a real sleep (say, putting none into pm_test), then:
* the notebook goes to sleep; * when I press the power button, the machine power itself off; * a few seconds after that, it powers itself on again.
Unfortunately, at this point, *everything* is black in the monitor and there are no responses (not even Magic SysRq).
The range of kernels tested was: 2.6.24 to 2.6.31-rc5.
As can be obviously seen from the kernels and the original report date, this bug is more than one year old (it was filed with bugzilla on 2008-10-07).
Please, help.
Thanks, Rogério Brito.
