pm-utils - reboot instead of resume from suspend after 2.6.34 because NVS saving

[Vladimir Hidalgo]

Binary package hint: pm-utils

Fresh 10.04 install does suspend on this VAIO VPCEB15EL, after an upgrade to 10.10 suspend works no more.

Laptop does suspend, but reboots when I try to wake it up, losing anything I was working on.

Now I can't close the lid without shutting it down first!

Looks like i'm not alone:

Tried the pm-suspend --quirk-s3-mode but laptop still restarts after resume.

Curiosity: if I switch to TTY1 with Ctrl+Alt+F1 and close the lid, lid turn off, and the laptop can wake up sucessfully

I don't know if it's not doing full suspend hence avoiding the error :\

Installed Kernel: Linux 2.6.34-020634-generic #020634 SMP Mon May 17 20:34:55 UTC 2010

Suspend does work.

I'll attach suspend log for 2.6.34 and 2.6.35

[Vladimir Hidalgo (vlad88sv)]

I don't mind using 2.6.34 ('cause it works better than 2.6.35 for me anyway, compat-wireless is broken with 2.6.35) but I think it's going to break suspend on more laptop models than my VAIO VPCEB15EL.

Please review this bug!

[Vladimir Hidalgo (vlad88sv)]

It's any way I can make pm-utils more verbose?

[Vladimir Hidalgo (vlad88sv)]

Just updated to Natty today and this is fixed.

[Vladimir Hidalgo (vlad88sv)]

My previous comment was wrong, this is still a bug in 2.6.38 kernel.

I think this is critical because: if a person closes the laptop lid then laptop won't enter stand-by mode, thus getting really hot and a non techie person would not notice this, probably burning his laptop.

BTW last working kernel was:
Linux protecsal 2.6.34-020634-generic #020634 SMP Mon May 17 20:34:55 UTC 2010 i686 i686 i386 GNU/Linux

Finally, took me almost 1 year, but Arch developers found it.

Reboot instead of resume from suspend

This problem started when saving NVS area during suspend was introduced (in 2.6.35-rc4) (mailing list post). However, it is known that this mechanism does not work on all machines, so the kernel developers allow the user to disable it with the help of the acpi_sleep=nonvs kernel command line option. This option could be pass to the kernel through GRUB options by editing the file /boot/grub/menu.lst (GRUB 0.97) on the kernel line.
Resume from suspend shuts down instead of wake up

On an Acer Aspire AS3810TG, resuming from suspend shuts down the computer instead of waking it up. If you experience a similar issue, try passing the parameter i8042.reset=1 to your kernel. In GRUB, the line in /boot/grub/menu.lst should be something like this:

kernel /vmlinuz26 root=/dev/vg00/root resume=/dev/vg00/swap i8042.reset=1 ro

Although I have not tested this, you could also set this parameter live without having to restart by doing:

# sysctl -e -w i8042.reset=1

It works like a charm and I can finally use newer Kernel than 2.6.34

On Ubuntu 11.10 you need to edit /etc/default/grub and change this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_sleep=nonvs"

And then refresh grub2:

sudo update-grub2

This may affect all VAIO Serie E and other similar devices.

Maybe CONFIG_SONY_LAPT (sony-laptop driver) may turn this off?

Keng-Yu Lin, sorry for adding you to this bug, but I saw this in Kernel changes:

Keng-Yu Lin (1):
      ACPI / PM: Do not save/restore NVS on Asus K54C/K54HR

I hope you could do the same for this VAIO model.

I've just installed daily 11.04 x86_64 from ISO image (downloaded today) and still needs the "acpi_sleep=nonvs" hack.

This is a fairly common laptop (because it's cheap) so there's potentially a lot of users of ubuntu who can't suspend/hibernate by default, it took me to solve it from 2010-09-27 to 2012-01-08 acording this bug report.

1 Year and a half has passed since reported and seems nobody cares, it's not I'm demanding anybody to fix it as I'm not paying anyone to do it, but this make bug reporting an useless tool, I've been reporting bugs in the past, but seems nobody really cares about it, so from now on I will just fix what is wrong without "bug reporting it".

Raring Ringtail: bug still present.

Fixed in version pm-utils/1.4.1-10
