D600 resume from RAM with black screen, ethernet tg3 is buggy

D600 resume from RAM with black screen, ethernet tg3 is buggy

[Petr Olivka]

Hi!

   Here is some of my result with D600:

   2.4.22 + swsuspend
     suspend to disk seems to work with small problems, but not tested 
hardly and is not much faster then reboot.

   2.6.0-test5 + test5-pm2.diff - kernel without modules, static

      - suspend "standby" do not switch off lcd. Is it ok?

      -suspend to ram work, but after resume is display black. Without 
test5-pm2 do not resume back and hang with black screen.

      -suspend to disk hang after hdc and hda suspended (hda is used for 
resume, why is suspended?). result:

....
hda: start_power_step(step: 0)
hda: start_power_step(step: 1)
hda: complete_power_step(step: 1, stat: 50:, err: 0)
hda: completing PM request, suspend
PM: Attempting to suspend to disk.

... and hang

I unable to use tg3 ethernet driver, because kernel fail somewhere in 
tg3  driver everytime I try suspend (backtrace list is too long on 
screen and I unable to scroll back).

Where are problems? How can I help to solve them?

thanks
   poli

p.s.

+/- yes.

So with -test5-pm2 machine resumes okay, you can type commands
etc, but can't see anything? Try passing cmd line
option acpi_sleep=s3_mode (or how is it called)...

Thats okay, we want to suspend hda, save its state,
resume hda, save state to hda, suspend hda, powerdown.

Can you mail me diff between vanilla and -test5-pm2?
Can you try suspending with echo 4 > /proc/acpi/sleep?
(that should call old working code... provided it propagates down correctly).

hm, s3_mode and s3_bios reboot computer, when I did try resume.
I did test "echo 3 > /proc/acpi/sleep" and "echo -n "mem" >
/sys/power/state".

I am using 2.6.0-test5 with patch recomended in acpi devel list
"test5-pm2", not vanilla.

"echo 4 > /proc/acpi/sleep" do nothing.

Try -test6 with echo -n mem, that seem works here. If both s3_mode and
s3_bios reboot computer, tough. That means that you either need to
find out another ugly hack (like s3_mode and s3_bios), or get specs
for your video card and write proper resume support (get the specs is
the hard part here).
