I'm currently trying out suspend (S3) on a few machines but none of them wakes
up completely/properly (I have a few more hosts I'm planning to try suspend
on once I can get useful information out of those not waking up properly).
Tested kernels: 2.6.24(-rc8), on one 2.6.23.8
To suspend I enter the following from console:
echo -n mem > /sys/power/state
Fujitsu-Siemens S7020 laptop (i915GM based):
Works fine except backlight that remains asleep and Xorg vesa driver
crashing Xorg.
It looks like a suspend cycle discards the VideoBIOS shadow copy.
Adjusting brightness using hotkeys or acpi-fujitsusiemens does not help
waking up the backlight.
At best backlight comes back when suspending from Xorg with
xf86-video-intel-2.2.x but then mode is distorded. Any attempt to fix this
using xrandr or switch to/from console puts backlight asleep.
Acer Travelmate 660 laptop (i855GM based):
Laptop suspends as expected but hangs while waking up.
Desktop with MSI nforce based mainboard with Athlon CPU, onboard graphics and
hdd on HighPoint RR1640 PCI card (USB mouse & keyboard):
Suspends as expected but hangs while waking up.
During wakeup I can ping the computer but userspace does not respond (e.g.
no answer when trying to connect via ssh)
The display remains off if using vga text console, display comes back with
garbadge when using nvidiafb (no Xorg running), USB is powered but triggers
no reactions on keyboard/mouse input
I tried using netconsole on the desktop computer to capture eventual printks
during resume but I got not a line during wakup. (only suspend progress
messages before actual suspend)
What can I do to get more information out of those two last machines and find
out why they don't wake-up properly?
I can provide more details on each of those machines if it can help (lspci,
kernel config, peripherials, acpidump)
Regards,
Bruno

Bonjour, it seems for me that using echo isn't the right way. You could
follow instructions at the end of:

Please try s2ram (http://suspend.sf.net/s2ram-support.html).

This one is on the s2ram whitelist, should work.

This might work with "s2ram -f --vbe_post --vbe_save", please try.

What kind?

Please apply the patches 01-11 from:
http://www.sisk.pl/kernel/hibernation_and_suspend/2.6.24/patches/
on top of 2.6.24, compile the kernel and install it. After booting, please do:
# echo core > /sys/power/pm_test
# echo mem > /sys/power/state
and see if the boxes survive it (this causes the suspend/resume sequence to
be executed without acutally suspending, but busy-waiting for 5 sec. instead).
Greetings,
Rafael

Thanks for the pointer, using version 0.8 as available in Gentoo portage for my tests.

Backlight comes back with vesafb using s2ram, not yet tested with intelfb or Xorg.
Ideally the kernel would be able to recover this without the hacks by s2ram (vesafb
post the videobios -- intelfb (or xf86-video-intel for X) would be able to properly
configure the graphics).
For the intel drivers the problem is probably missing specs from Intel...

This test passed (K7N420) with minimal amount of modules loaded (text-mode graphics).
Real suspend worked as well (s2ram -f --vbe_post) but it's not the right tuning to
get usable console back. Currently results in scrambled output with half of the
character placeholders flickering at cursor speed. (will test other options of this
version of s2ram, possibly upgrading to latest to get more options as descibed on
suspend.sf.net).
It takes about 1 minute between the moment when the first ping reply and
userspace/display wakeup or netconsole messages.
More details to come as I get time to do more complete tests with all drivers.
