Aspire One can't hibernate

[Mathieu Trudel-Lapierre]

Trying to hibernate this Acer Aspire One model we have in the lab but hibernate doesn't complete: the system goes back to screensaver and asking for a password. However, the power button LED starts blinking as in suspended mode (although the system doesn't suspend following this). It needs to be restarted before the button LED will get back to the "normal" green state.

Well, seems like this may actually be an issue with the partitioning scheme, as there is a "Not enough free swap" message in syslog (and I finally could see the message once on another netbook). Marking as Incomplete, we should first test with a different partitioning scheme.

Hi Matthieu,

I have an Aspire One ZG5 which is AOA110 and when I tried this week to install 10.10 from a usb "try it" version, downloaded from our site I wouldnt even boot. You seem to have better luck than me.

Do we have different models or is the cert process doing differently to what a user would do?

Mathieu,

Any update on the re-test as mentioned in comment #2?

[Mathieu Trudel-Lapierre (cyphermox)]

Hibernation works fine after setting custom partitions. Here is what I think happens:

This system is the model with an SSD drive, which is so small the code that decides what size swap to use for guided- use entire disk guesses a space that is too small to hold the entire contents of RAM, so hibernate fails.

This time I used ~6G for /, which left about 2.1G for swap, and hibernate succeeded.

Victor, I couldn't say why your system won't boot. The model I'm using is also a ZG5 AOA110, so maybe it has to do with a BIOS update required (I vaguely recall something similar to this early on when they were released or with early models).

[Ameet Paranjape (ameetp)]

Thanks Mathieu. I will double check with the kernel team if this issue requires documentation or a legitimate bug fix. Could you add the output of 'fdisk -l' for the working and non-working situations.

Victor, Please open a new bug for your issue. Thanks.

A "bad" partitioning scheme goes like this:

Disk /dev/sda: 8069 MB, 8069677056 bytes
255 heads, 63 sectors/track, 981 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0006fbcd

   Device Boot Start End Blocks Id System
/dev/sda1 1 933 7490560 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 933 981 387073 5 Extended
Partition 2 does not end on cylinder boundary.
/dev/sda5 933 981 387072 82 Linux swap / Solaris

While with manual partitioning ("good"), on which hibernate succeeds:

Disk /dev/sda: 8069 MB, 8069677056 bytes
255 heads, 63 sectors/track, 981 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0004e831

   Device Boot Start End Blocks Id System
/dev/sda1 * 1 730 5858304 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 730 981 2019329 5 Extended
Partition 2 does not end on cylinder boundary.
/dev/sda5 730 981 2019328 82 Linux swap / Solaris

The bad partitioning case has indeed a swap very low in size: around 378MB, insufficient for 1GB of RAM of this machine. Kernel not at fault in this case.

There is a nice faq about swap here: https://help.ubuntu.com/community/SwapFaq

Not sure if more documentation is needed. I changed this to invalid, if not ok please reset it.
