[solved] Unloading modules before suspend to disk

Hi, I'm trying to get my Asus U36jc to suspend to disk and resume. Suspending seems to go fine, but after resuming I get an unresponsive notebook (no response on key presses or ping) showing a black screen. Then immediately the fan gets louder and the notebook gets warmer.
Just before the machine goes to sleep, I see this in my screen:
xhci_hcd 0000:04:00.0: PCI post-resume error -110!
xhci_hcd 0000:04:00.0: HC died; cleaning up
xhci_hcd 0000:04:00.0: HC died; cleaning up
dpm_run_callback(): pci_pm_resume+0x0/0xb0 returns -110
PM: Device 0000:04:00.0 failed to resume async: error -110
hda-codec: out of range cmd 0:20:400:fffff7ff
I found this guide (https://www.kernel.org/doc/Documentatio … ugging.txt) and using that I determined that when I first remove modules ehci_pci, ehci_hcd and xhci_hcd, suspend to disk and resume seem to work fine.
I found out here (https://wiki.archlinux.org/index.php/Pm … end_to_RAM) how to unload modules prior to suspending to RAM, but that doesn't seem to work for suspend to disk, and I can't find how to unload modules prior to that. Can someone tell me how to do that?
Thanks for any help!

I'm not sure if pm-utils is deprecated, it doesn't say so here (https://wiki.archlinux.org/index.php/Pm-utils). In any case its a dependency of upower, which is a dependency of kdelibs, so as long as I want to use KDE my harddrive is stuck with it.
However, I decided to try your suggestion to use systemd:
# asus36JC.service
[Unit]
Description=Script upon suspend/resume
Before=sleep.target
StopWhenUnneeded=no
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/home/diederick/bin/no_modules
ExecStop=/home/diederick/bin/modules
[Install]
WantedBy=sleep.target
It seemed to work perfectly for a couple of times in a row (modules were there before and afterwards) until I restarted the notebook, when the problem was back. But then I remembered to enable the service and now it works. Thanks a lot!

[solved] unload module alx on suspend fails

Hi!
I'm having trouble getting my ethernet card to work properly with suspend to ram (pm-suspend). Its a Qualcomm Atheros AR8161 Gigabit Ethernet Adapter (builtin ethernet-card of the Asus N56VZ) that I'm running with the alx-module that I build from the compat-drivers (compat-drivers-3.9-rc2-2-su, so version 1.2.3 of the alx module) on kernel 3.8.8-2. The driver works fine except it breaks suspend. A first suspend works fine (see suspend.log, upper part), however, after resuming, NetworkManager does not detect a cable being plugged in. Trying to suspend again fails results in the lower part of suspend.log. Removing and probing the module again (reload.log) seems to work fine and resets the whole thing (network works, one suspend works, all following do not work)
Logs see https://gist.github.com/anonymous/5467609
I created a file SUSPEND_MODULES="alx" /etc/pm/config.d/modules (rights 644) that as far as I understand is supposed to unload and load the module upon suspend and resume but for some reason this does not seem to work properly. Why is that, am I just missing a typo? How can I fix it?
Any help is appreciated!

„Sleep hooks
Systemd does not use pm-utils to put the machine to sleep when using systemctl suspend, systemctl hibernate or systemctl hybrid-sleep; pm-utils hooks, including any custom hooks, will not be run. However, systemd provides two similar mechanisms to run custom scripts on these events.” – from wiki, so the sad thing is it's not as easy as in Ubuntu.
But (I guess) it's not impossible. I've got the same problem with ALX so I'm gonna try to make my own hook based on Wiki tips. Currently this Wiki page https://wiki.archlinux.org/index.php/Pm-utilspm is outdated (for Systemd user), so I'll try this section https://wiki.archlinux.org/index.php/Sy … management .

Computer reboot instead of resume after suspend to disk

Hi,
I install minimal KDE on my laptop. Everything work fine but suspend.
- When I suspend to disk, initially it seem to work well. when I press power button, system act a new boot, not resume the session before.
- When I suspend to ram, everything work well: it really suspend, lock screen and reactive when press Enter, application work normally but I cannot re-connect to network. I use wicd as network manager, it always show popup: "Unable get IP from ..."

Yes, that's normal and should work.
Looking at the module list maybe try stopping the video4linux before suspend.
To double check: boast, you rebuilt the kernel, yes?

Systemd and suspend to disk

Hello,
I have the same problem as described in this bug:
[systemd] hibernation does not work: https://bugs.archlinux.org/task/37028
I followed the report to:
Dave Reisner (falconindy) wrote:
Therefore: If you want the resume hook to work with the systemd hook, you need to go write code. You have a few options:
1) Write a generalized solution for running the shell based hooks under systemd.
2) Write an sd-resume hook which replicates the functionality of the resume hook.
3) Write some other method of writing the resume device major:minor to /sys/power/resume which doesn't take place in early userspace. I'd bet that, for a lot of systems, you might even be able to get away with using tmpfiles.d for this.
Due to the lack of knowledge for 1) and 2), I went for 3):
cat /etc/tmpfiles.d/resume.conf
w /sys/power/resume - - - - 8:8
which also writes successfully the 8:8 in my /sys/power/resume .
However, it does not work.
If I want to resume from my suspend to disk I get "root not clean, recovering journal" etc. and I'm at a fresh session.
Any ideas?

I tried it and I can confirm that using tmpfiles.d doesn't work here either.
You're right that there's not so much to see in the previous boot. At the end of the log, when hibernating:
Mar 08 21:51:03 amd64box systemd[1]: Starting Sleep.
Mar 08 21:51:03 amd64box systemd[1]: Reached target Sleep.

Mar 08 21:51:03 amd64box systemd-sleep[3523]: Suspending system...
I can see harddisk activity and I believe that the image is written correctly to the disk.
I think the problem is when resuming. Before the systemd initrd starts I can see the lines:
Mar 08 21:51:48 localhost kernel: PM: Checking hibernation image partition /dev/sda2
Mar 08 21:51:48 localhost kernel: PM: Hibernation image not present or could not be loaded.
Later in the boot:

Mar 08 21:52:00 amd64box kernel: Adding 2104508k swap on /dev/sda2. Priority:-1 extents:1 across:2104508k FS

Mar 08 21:52:00 amd64box systemd[1]: Starting Swap.
Mar 08 21:52:00 amd64box systemd[1]: Reached target Swap.
[*1]
And a bit later when the tmpfiles service is executed:
Mar 08 21:52:03 amd64box systemd[1]: Starting Create Volatile Files and Directories...
Mar 08 21:52:03 amd64box systemd[1]: Starting Trigger Flushing of Journal to Persistent Storage...

Mar 08 21:52:03 amd64box systemd[1]: Started Create Volatile Files and Directories.
Despite that it's not working I believe it's a bit late to resume when using the regular tmpfiles.d (rootfs got already checked and corruption detected, the above swap message about rewriting it's signature, which I'm not sure what it means etc.).
Therefor I tried to enforce the execution of the systemd-tmpfiles-setup service in the early systemd initrd (which it didn't do before), by a custom hook.
Unfortunately the result is very similar to above:

[SOLVED] Xfce4 Lock after suspend

Hello everyone,
I know that there was it already asked, but in my question is something different. Is there any option to lock screen with LightDM in Xfce4 when is system going to suspend ? I already edited /usr/bin/xflock4 and it locks screen when is executed from terminal or simply locked from xfce panel, but it doesn't lock screen when i suspend computer. In power manager and in session settings is option already ticked to lock the screen after suspend.
PS: I know that "dm-tool lock" doesn't really lock the screen only redirect you to tty2.
EDIT: Now it works so here is solution:
1. Install light-locker
pacman -S light-locker
2. Create systemd service
nano /etc/systemd/system/lock.service
[Unit]
Description=Lock X session
Before=suspend.target
[Service]
Type=oneshot
ExecStart=/usr/bin/xflock4
[Install]
WantedBy=suspend.target
3. Enable systemd service
systemctl enable lock
4. Add light-locker to xflock4 script
nano /usr/bin/xflock4
#!/bin/sh
light-locker-command -l

Testing Function Module before using in DataSource?

Hi Experts,
After writing a Function module for Transaction DataSouce (by copying RSAX_BIW_GET_DATA_SIMPLE), is there any way to test the Function Module before using in Transaction DataSource? (to see how many records it retrieves).
Also can somebody please throw some light in understanding the source code of RSAX_BIW_GET_DATA_SIMPLE function module, as it has many declarations like E_T_DATA,
I_T_SELECT which will be used in the new function module?
Looks like, the function module RSAX_BIW_GET_DATA_SIMPLE uses only one table SPFLI.
If it is just one table why do we need to write function module to extract data?
Forgive me for my lack of ABAP knowledge.
Thank you,
Lakshmi

The generic function moduel is used when there is no BW extractor and you cannot get to the data via a view or table
The extractor is quite simple
You create a extract strcuture of data to send to BW
Then you create the function module - e_t_data takes on the extract structure
The select options read data via the infopackage selection from BW (and thus when you create your datasource you shoudl click the fields to be select option)
So in the ABAP
You read the select option and put them into a range
You select from which ever tables you need to in R3 and put into an itab
You then loop aroudn the itab and manipulate the data or read other tables
The data finally ends up in e_t_data
The whole thing gets looped around based on the size of the data package - ie if it is 10000 records then the fetch next cursor after 10000 records will send the package of e_t_data out to the refc scheduler and down the line to BW - then the fetch next cursor will get the next 10000 records for the next
I use this all the tiem (so sorry for the brain dump)
I especially use it for virtual cubes - ie to get real time data from R3 from within BW - the data is not requested by ipak but by the query at runtime against a Virtual cube which connects to this generic extractor
Note: this generic extractor can also live on the BW side - ie you can use it instead of APD to snapshot cube or DSO data to send as an ipak into another cube

Suspend to disk

Hi
Can i ge my mbp to suspend to disk instead do ram immediatly after closing the lid, or via a command?
Thanx for any help
Selon

There are two solutions:
1. Remove A/C power, then remove the battery for about 10 seconds. The computer will automatically go into Safe Sleep mode.
2. Open your Terminal app (Utilities folder) and at the prompt enter the following command line followed by a return:
prompt> sudo pmset -a hibernatemode 1
You will be prompted for your password which will not be echoed. Quit the Terminal app.
From now on your computer will automatically go into Safe Sleep (hibernate) mode when you close the lid. To return to the normal sleep mode open the Terminal app and enter the above command line but change the "1" to a "3".

How to load kernel module before another kernel module?

I have an Iomega ZIP 100 parallel port drive and need module imm to be loaded before lp module. But I don't know how to do this. Simple adding these modules in rc.conf in MODULES section in the correct order doesn't work. I also realized that udev loads lp module, but I don't know how to make udev load this module before or after other modules.
Last edited by kotyz (2007-06-24 13:58:15)

or in /etc/mkinitcpio.conf :
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES="piix ide_disk reiserfs"
MODULES=""
and make a new initrd image with mkinitcpio -g /boot/newkernel26.img ,edit menu.lst and reboot

Problems with waking from standby (suspend to disk)

Hello,
I have a late-2010 MacBook Air 11.6". I am running Lion 10.7.2.
To save battery life and also increase data protection via FileVault 2, I set the hibernatemode to 25 (alwas immediately suspend to disk) and enabled destruction of the FV key on standby (pmset -a hibernatemode 25 DestroyFVKeyOnStandby). Suspending works fine; and when I open the lid to resume from standby, I get the password prompt for FileVault's full disk encryption. After entering the password, the resume process starts. But then in some cases, my display stays black and I cannot turn it on again (tried closing/opening the lid, pressing Ctrl+Shift+Eject, connecting external monitor, ...)
If this behavior occurs, I can find entries like the following in my kernel.log:
Dec 23 13:30:15 mba kernel[0]: NVDA::setPowerState(0xffffff800c6b3000, 0 -> 2) timed out after 61662 ms
Is that a hardware bug? Any idea how I could possibly work around it?
Any help would be greatly appreciated!
Best Regards

Unloading Modules in Flex

What does the debug trace [Unload SWF] mean?
As per this blog
http://blogs.adobe.com/tomsugden/2010/02/how_to_unload_modules_effectively.html
"This trace indicates that the module have been successfully unloaded"
Is this true?
I am unloading a module, I see the [Unload SWF] trace, but after unloading, if I try to create an object of a class contained in the unloaded module (using reflection), I am still able to create it.
Am I understanding it wrong?
Thanks!

That means that the bytes of the SWF have been removed from memory. I'm not
sure if you're just getting lucky or if there is some other thing going on.

[Solved] Suspend to Disk: systemd-hibernate.service Fails

Howdy-ha, folks. I know this looks pretty mundane, but for the life of me I can't get hibernation to work. Each time I run systemctl hibernate the screen will go blank as though preparing to suspend, then come back on; journalctl shows the same error messages:
PM: Cannot find swap device, try swapon -a.
PM: Cannot get swap writer
Failed to start Hibernate.
Dependency failed for Hibernate.
Service sleep.target is not needed anymore. Stopping.
Unit systemd-hibernate.service entered failed state.
This happens when swap is mounted, and "swapon" says as much. I've been working on this for about four hours now, and none of what I've found seems to pertain to my situation (most of the "solutions" were "Increase partition size').
What I've tried:
- Three different kernels---linux-ck custom build and linux-ck-sandybridge from graysky's repo (both with BFQ and CFQ: see below), as well as the stock Arch kernel
- A 2 Gb swap file at /swapfile on my SSD;
- A 4 Gb swap partition on /dev/mmcblk0 (an SD card, and my preferred method/location, if possible);
- An 8 Gb swap partition on HDD /dev/sdb2
Reasons for wanting hibernate rather than suspend-to-RAM:
- Maximize battery life.
- There's some kind of issue with Linux-ck and suspending to RAM; it'll work once, then freeze in a kernel panic the second time, forcing a hard reset. The stock kernel suspends to RAM, but still won't hibernate
- I put a lot of time into building a custom Linux-ck kernel, and would rather not have to start the configuration over with the stock kernel if possible.
I'm working with limited space on my boot drive and, as mentioned, increasing the amount of swap has no bearing on this. The resulting phenomenon and error messages are the same, regardless of size and medium. I've exhausted my ideas on where to look, and what to even look for. Thanks a lot to everyone in advance (especially you,karol; don't think I don't see you lurking back there )

[Solved]PM: swap header not found attempting to suspend encrypted disk

Hi all,
I have my root partition set up as a dm-crypt encrypted volume, and I followed the instructions here to set up a swap file.
I also followed these instructions to add the resume hook to my mkinitcpio.conf between encrypt and filesystems.
I modified the /etc/default/grub file like so:
GRUB_CMDLINE_LINUX_DEFAULT="cryptdevice=/dev/disk/by-uuid/0cb6b266-ce81-4b2f-9958-722c788c46ef:cryptroot cryptkey=/dev/disk/by-uuid/18868ab9-e0dd-4634-9f9e-69f3d3686d3f:ext2:/laptopkey root=/dev/mapper/cryptroot resume=/dev/mapper/cryptroot resume_offset=4952064"
I determined the offset using the swap-offset tool provided by the uswsusp package.
And I ran
mkinitcpio -p linux
and
grub-mkconfig
When I type "systemctl hibernate" the system begins to hibernate, then comes back up immediately. Journalctl -xn gives this:

I think one of them is the actual device, the other is the dm-crypt container? I guess I could try both...I'll report back.
Usually I use the output of blkid to find out the correct uuid. The uuid to use for / or swap is the one pointing to one of /dev/dm*.
LeftyAce wrote:For the record I am using resume=/dev/mapper/cryptroot. I think since the swapfile is a file not a block device in my case that's important. Since the encrypt hook runs first, that mapper volume is present and unlocked by the time resume comes around.
In my case the same happens but for some reason it doesn't seem to work, and I've been procrastinating submitting a bug (I use hibernation very rarely and I know of a way that works).

[solved] powersaved does not resume after suspend to disk

Hello,
I've just changed over Arch Linux and this is the first time i'm using the distro, migrating from slackware. Anytime I do a powersave -U through the CLI, my notebook shuts down and swsusp writes to my swap but on resuming the notebook boots back like it would normally with an invalid swap signature.

Figured it out. The problem was with hooks.
So I edited, the /etc/mkinitcpio.conf file, added resume to the HOOKS="" section and then ran mkinitcpio -g /boot/vmlinuz26-rev.img
That created the initrd image and i replaced the existing image in grub with the newly created one.
