Several problems with sleep states

Several problems with sleep states

[Nicolas Sabouret]

Hi,

following problems:
1. echo -n "disk" > /sys/power/state => nothing happens
2. echo -n "mem" > /sys/power/state => the computer enters "suspend on 
ram" mode (the suspend light gets on, etc...) when I try to wake up the 
computer, it hangs (some noise indicating that the disks are woken up 
and then nothing but a blank screen, even starting from console).

3. It has certainly nothing to do with what I said before, but I cannot 
find a /proc/acpi/processor/CPU0/performance (I have all the other files 
you mention in your Documentation section).

Here is an output of dmesg | grep acpi :

be sure to disable usb and sound *before* going to sleep. Your
/proc/interrupts give me the idea that you have sound and usb enabled,
which is not good.

Also, if you have a radeon gfx card, you wont get your console frame
buffer back to life yet. If you use the ATI-Binary drivers, you wont get
x11 back to life. If you use the kernel ati drivers for x11 with no
framebuffer, you should be abled to resume an x11 session.

Regards, P.

You should try with swsusp instead and with /proc/acpi/sleep by now.
pmdisk apparently does support only S4BIOS (and you don't have s4bios,
looking the dmesg), not S4.

It has been deprecated.  Look at /sys/devices/system/cpu0/cpufreq instead.

On the contrary, the current radeonfb from 2.6.3 does restore the console
contents. That said, the backlight might still be a problem, but this is
usually independent of the display driver.

It does support plain S4, at least it sorta-works for me.

Ok, then I guess those comments in drivers/acpi/main.c


        /* do we have a wakeup address for S2 and S3? */
        /* Here, we support only S4BIOS, those we set the wakeup address
        /* S4OS is only supported for now via swsusp.. */

are no more appropriate?

Actually, I had no success with 2.6.3-mm4 and the new radeonfb driver
for restoring the console. Even worse, using the radeonfb driver, I was
not abled to restore x11 anymore. Using the patch Giridhar Pemmasani
posted here some days ago, I was abled to get the backlight back, but
still no resume of the console, (Ati Radeon 9000 Mobility, I think its
R250). Its not that bad for me, its cool that x11 works :-)

With best regards, P.

There are 3 different S4 implementations currently, 2 of which (Pavel's 
swsusp and Pat's pmdisk) are in 2.6. The third is Nigel's swsusp2 available
as a patch from http://swsusp.sf.net
