Cool, much thanks Maxim! The bug should not be closed though, since it's not fixed in Maverick yet. I've also opened a task for Lucid since the patch could be backported to benefit Acer users. For kernel developers, here's the commit message: ACPI: Store NVS state even when entering suspend to RAM https://bugzilla.kernel.org/show_bug.cgi?id=13931 describes a bug where a system fails to successfully resume after the second suspend. Maxim Levitsky discovered that this could be rectified by forcibly saving and restoring the ACPI non-volatile state. The spec indicates that this is only required for S4, but testing the behaviour of Windows by adding an ACPI NVS region to qemu's e820 map and registering a custom memory read/write handler reveals that it's saved and restored even over suspend to RAM. We should mimic that behaviour to avoid other broken platforms. ** Changed in: linux (Ubuntu) Status: Fix Released = Triaged ** Changed in: linux (Ubuntu) Assignee: Maxim Levitsky (maximlevitsky) = (unassigned) -- Acer Aspire 5720 hangs on second resume from suspend, i.e. suspends only once [BIOS PROBLEM] https://bugs.launchpad.net/bugs/160763 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

For these of you who are too lazy/busy/... compiling the kernel, here is userspace workaround. Compile attached program writereg.c (gcc -owritereg writereg.c), put it in /usr/local/bin, and then use attached script, make_s2ram_work after first resume. If the output is something like (you see FF): writing 0 to address (current value = FF) Then its likely that my fix works. Try to suspend again. If works then you can use this script after each suspend to clear the state that causes the hang on following resume -- Acer Aspire 5720 hangs on second resume from suspend, i.e. suspends only once [BIOS PROBLEM] https://bugs.launchpad.net/bugs/160763 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Maxim... you're AWESOME!! Thanks for the effort!! I've tried to apply the patch against the 2.6.34 kernel from git, but patch prints a strange output: Hunk #1 succeeded at 213 (offset -3 lines). Hunk #2 succeeded at 590 with fuzz 2 (offset 292 lines). Indeed, it applies the hunk #2 to a completely different function (acpi_hibernation_finish()) rather than acpi_suspend_finish(), that simply doesn't exist in my sleep.c.

I've tried to apply the patch against the 2.6.34 kernel from git, but
patch prints a strange output:
Hunk #1 succeeded at 213 (offset -3 lines).
Hunk #2 succeeded at 590 with fuzz 2 (offset 292 lines).
2.6.34 from git it no longer 2.6.34...
now merge window is open, and lot of stuff was merged it.
Still its strange, because I just switched to that kernel now, and my
patch applies.
To be honest I used wireless-testing + nouveau master + few my own
patches.
But I really don't think this matters.
This is the patch I use now:

power: store/restore NVS area on suspend to ram too
This fixes suspend on my notebook.
This is probably workaround around bug in bios,
but maybe The Other OS also does that?

This problem has been posted in Ubuntuforums
(http://ubuntuforums.org/showthread.php?t=600450
), but got no answer.
My Acer Aspire 5720 running Ubuntu Gutsy 7.10 is unable to resume
from a standby when another standby/resume has occurred. The power
LED turns from blinking orange to stable green, but screen backlight
remains off and - I suppose - the processor fan stays off too. I can
hear the hard drive and CD-ROM spinning up, but the system is
completely unresponsive. I have to turn it off pressing the power
key long enough.
On Windows XP and Vista, standby works OK.
*UPDATE*
this is BIOS problem. system hangs early and doesn't pass control to
Linux.
Linux has no chance to bring system back.
It not possible to understand what triggers that BIOS hang.
It probably is some bug that by chance doesn't trigger on windows.
These are the attempts made so far. Where not specified, nothing
changed in the behaviour.
- adding ec_intr=0 to the boot cmdline;
- adding acpi_osi=!Linux;
- executing Ubuntu in single-user mode, using /etc/acpi/sleep.sh to
sleep;
toggling the following flags in /etc/default/acpi-support, one by one:
- ACPI_SLEEP_MODE=standby - the script stops and says echo: write:
No such device writing 'standby' to /sys/power/state
- SAVE_VBE_STATE=false
- POST_VIDEO=false
- USE_DPMS=false
- DISABLE_DMA=true
- RESET_DRIVE=true

- DOUBLE_CONSOLE_SW=true
- toggling more than one flag like described here:
http://de.wikibooks.org/wiki/Asus_W3N-Kompendium:_Ubuntu_Suspend_to_Ram
- hangs on first resume
- disabling all services in /etc/rcS.d, then killing most of the
processes, then removing most of the modules;
- adding noapic nolapic to the boot cmdline - hangs on first
resume;
- adding pci=routeirq to the boot cmdline;
- toggling BIOS SATA emulation from AHCI to PATA;
- disabling all scripts in /etc/acpi/{suspend,resume}.d - apart
from the screen unable to work at first resume, nothing changed;
- upgrading BIOS from 1.14 to 1.19;
I followed the instructions at https://wiki.ubuntu.com/DebuggingKernelSuspend
. If I execute that command even for first standby, at next reboot I
have these data:
Magic number: 0:35:185
hash matches drivers/base/power/resume.c:57

Any help is VERY appreciated! This is definitely the bug that keeps
me to using Linux for everyday work...

Well that is obvious, thats why I never bothered to contact their support in
first place.
However if we were to act together, it might work.
I remember a story about one motherboard vendor that placed anti-linux checks
(due to stupidity though) in the ACPI tables.
This prevented suspend, became public, and they eventually fixed it.
Remember, the only way to fix that bug is to make acer fix the BIOS,
because it hands on resume, not linux!.
