Problems with 600m PM states

Problems with 600m PM states

[Michael A. Smith]

I have been unable to get any type of sleep to work with this laptop and
the 2.6.0 vanilla kernel.

Let's start with S1 and work up from there.

 echo 1 > /proc/acpi/sleep

Generates...

 Stopping tasks: ========|
 hdc: start_power_step(step: 0)
 hdc: completing PM request, suspend
 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: Entering state.
  hwsleep-0257 [23] acpi_enter_sleep_state: Entering sleep state [S1]

...and it appears to be in standby.  The power led goes from solid on to
a blink.  Now, if I hit the power button to attempt resume, I get ...

 Back to C!
 PM: Finishing up.

... and that's it.  The power led is back on solid, but the system is
non-responsive.


For reference, I've tried to minimize the variables as much as possible.
I'm booting into single user mode and testing from there.  There are no
modules loaded.


Any help is appreciated, I'm happy to post more info or try any
suggestions.

Thanks,
Michael Smith

Maybe patches filed at
http://bugzilla.kernel.org/show_bug.cgi?id=1557   and
http://bugzilla.kernel.org/show_bug.cgi?id=1588
can help you.

Great!  The patch attached to this bug seemed to solve the problem for
S1.  I can now resume without issue from an S1 sleep.

Onto S3...

The system seems to suspend correctly, but will not resume.  After the
suspend, the power led has a slow blink, which is what I expect.  If I
hit the power button to bring it back, I can hear the disk spin up, and
the power led is on full, but that's it.  The screen never returns and
my only recourse is a hard reboot.

Please try 2.6.1-rc1 or -rc1-mm1 for the keyboard problem. Have you already
tried passing acpi_sleep={s3_mode,s3_bios} as a kernel parameter?

No, I will try them now.  Are these parameters documented somewhere?  What
do they control?

Tried 2.6.1-rc1 (with the S1 patch referenced earlier in the thread)
and see the same behavior for S3.  Not sure which keyboard problem you were
referring to though.

I have now.  If I use either, instead of resuming, the machine reboots.
Without any parameter, after resume the screen remains off, but it
appears the system is running ... if i blindly type "shutdown -h now",
the system will power off.

The most common case for S3 problems is a dead screen and a dead keyboard +
mouse, which results in a supposedly non-responsive system (the NIC is
usually fine, but then you need a second machine to check that). Since you
wrote about hard reboot, I assumed you tried ctrl+alt+del and it didn't
work, hence the keyboard problem.

Then you're probably out of luck for now. You may, as Pavel suggests, try
suspending from X, but it probably will reboot if you have AGP drivers
loaded.
