SubjectRe: [Bugme-new] [Bug 11717] New: Pressing suspend button suspends, but does not wakes up

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.
