Hi, I just managed to make the notebook go to sleep right (the screen
goes off, and the power button light oscillates, as in windows)


in loader.conf, anyway now when I try to wake it up, I can hear the HD
and DVD drive starting the resume process but it just hangs there, the
screen doesn't turn on, and I don't hear any beep even with
debug.acpi.resume_beep=1, I'm back again where I was in 6.1-STABLE
(now in 7-CURRENT), and keys doesn't work (ctrl + alt + del doesn't
start the reboot process, i have to press power button 5 seconds and
As I wrote before, setting debug.acpi.suspend_bonce=1, and using
acpiconf -s 3, leaves me again in the console after a few seconds
without turning off the screen or showing any errors.

Any ideas? At least how to get the screen on again?

Hi, today I finished upgrading to 7-CURRENT, and now the problem is different
I'm using the generic kernel, and modules are oly kernel, and acpi.ko.

When I do "acpiconf -s 3" with bounce=1 everything works ok (i mean it
seems to "bounce" ok, since after some seconds of delay (the screen
never goes off), I can continue using the console as before the
acpiconf -s 3 command), but when I do "acpiconf -s 3" without
bounce=1, it seems like the HD goes to sleep, but the screen keeps on,
and the power button led, doesn't "oscillate" as it does when I
suspend in Windows or as it did in suspend on 6.1-STABLE, it seems
like it doesn't finish the suspend process right.
So when I try to wake it up, pressing any button, even the power
button (although the screen is still on, showing the console where I
typed acpiconf -s 3), and after some keystrokes it starts beeping
forever (it's a constant beep, with, and without resume_beep=1). So I
have to shutdown everything pressing the power button 5 seconds, and
