 Posted: Sat May 06, 2006 8:36 am Post subject: Suspend2 unable to unload some modules |
 |
|
I am trying to get Suspend2 to work but there are some problems with module unloading | Code: | # hibernate
Some modules failed to unload: sony_acpi ipw2200 ieee80211 ieee80211_crypt nvidia firmware_class
Some modules failed to unload: nvidia
hibernate: Aborting suspend due to errors in ModulesUnloadBlacklist (use --force to override). |
I am using a Sony Vaio VGN-FS660...I guess I could build the ieee80211 and sony_acpi things in-kernel right? But as for the nvidia-kernel and the other modules, how can I make Suspend2 successfully do its job? I'm using media-video/nvidia-kernel-1.0.8756. This is my /etc/hibernate/hibernate.conf | Code: | ### suspend2 (for Software Suspend 2)
UseSuspend2 yes
Reboot no
EnableEscape yes
DefaultConsoleLevel 1
Compressor lzf
Encryptor none
# ImageSizeLimit 200
## useful for initrd usage:
# SuspendDevice swap:/dev/hda2
## Powerdown method - 3 for suspend-to-RAM, 4 for ACPI S4 sleep, 5 for poweroff
# PowerdownMethod 5
## Any other /proc/software_suspend setting can be set like so:
# ProcSetting expected_compression 50
## Or traditionally like this:
# Suspend2AllSettings 0 0 2056 65535 5
## Or even from the results of hibernate --save-settings with this:
# Suspend2AllSettingsFile /etc/hibernate/suspend-settings.conf
## For filewriter:
# FilewriterLocation /suspend_file 1000
# VerifyFilewriterResume2 yes
# ProcSetting userui_program /sbin/suspend2ui_text
### sysfs_power_state
## To use /sys/power/state to suspend your machine (which may offer
## suspend-to-RAM, suspend-to-disk, standby, etc) comment out all the options
## above for Software Suspend 2, below for acpi_sleep, and uncomment this line.
## You may replace mem with any one of the states from "cat /sys/power/state"
# UseSysfsPowerState mem
# PowerdownMethod shutdown
### acpi_sleep
## To use ACPI to suspend your machine (via /proc/acpi/sleep), comment out
## all the options above for Software Suspend 2 and sysfs, and uncomment this
## line. The number refers to the ACPI sleep state - 3 is suspend-to-RAM and
## 4 is suspend-to-disk.
# UseACPISleep 4

In your /etc/X11/xorg.conf, what is your AGP setting?

hmmm. I don't have it in my xorg.conf, but dmesg | grep agp returns | Code: | Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected an Intel 915GM Chipset.
agpgart: AGP aperture is 256M @ 0x0 |
what do I have to put in my xorg.conf?

It means that you are using the autodetection which turns to use the kernel's AgpGart driver. This driver does not allow the nvidia driver to unload properly (check nvidia readme). The best way to proceed is to keep AGP on (though it can be disabled completely) by specifying the nvidia's implementation:
| Code: | Section "Device"
Driver "nvidia"
...
Option "NvAGP" "1" # NvAgp
...
EndSection |

Try "hibernate --force". I found that my laptop suspends and resumes reliably even though some of the modules I use are blacklisted. If it works, just remove them from the blacklist.

Ok so apparently I was able to suspend successfully (i've only tried without using X, I'll try with X later) but I must say that I'm a bit taken back by the fact that it's as if I had shutdown normally...I mean, my computer booted up, I saw the grub screen, then I chose Linux and after doing checks to the Filesystem and whatnot, the hibernate image decompressed and took me back to where I was...how is that hibernating my computer? That's just improving boot time by about 5 seconds. Am I doing something wrong or is it just like that? I'm a bit let down, I thought that when I powered on my console would reappear straight away.  ..isn't that how it works with Windows and MacOS?

Well, I was kinda disapointed too concerning the speed. suspend has to take all your memory and compress it (it's even worth without compression owing to my slow laptop disk ) and finally writes it. When you restart, your complete kernel has to get initialized, then comes the uncompression and the write back in memory. Plus, there are couples of things that are not restored properly and some services must be restarted (for me I restart my wifi and hotplug services). Arggh!
Still, it remains interesting to find back your apps the same way they were started...
You can shorten this time by adjusting stuff in your /etc/hibernate/hibernate.conf. Here's mine as example:
| Code: | UseSuspend2 yes
EnableEscape no
DefaultConsoleLevel 0
Compressor lzf
Encryptor none
PowerdownMethod 4
Verbosity 0
LogFile /var/log/hibernate.log
LogVerbosity 0
Distribution gentoo
SaveClock restore-only
UnloadBlacklistedModules yes
LoadModules auto
DownInterfaces wlan0
UpInterfaces wlan0
RestartServices hotplug
SwitchToTextMode no
UseDummyXServer no
XStatus gnome
XSuspendText Sleep!
XResumeText Wake up! |
And I use fbsplash and gnome

There are 3 levels of suspend:
"Standby": It just switches a few things off and gives rather piddly power savings. I don't think anyone really uses this.
"Suspend to RAM": Computer everything it needs into the RAM and powers down everything except the RAM and a few essentials needed to power back. This is what Windows and MacOSX call "Sleep"
"Suspend to disk": This is what you've set up. It does a suspend to RAM, writes everything to disk, then shuts down. On the next boot, it reloads the image and restores your computer to how it was. Windows calls this "Hibernation".
Standby and Suspend to RAM take a few seconds to suspend and to restore, because they don't actually power down the computer. If you want fast suspending, use these. However, with these modes, your battery life will still decrease and will eventually run out. And if you use these modes and put it in your bag, your laptop might overheat (a guy I worked with fried his laptop doing this).
Suspend to disk is useful if you (for example) are on the train writing a report and get to your stop and have to move. You can hibernate your machine, and when you get to your next sitting position, you can switch your machine back on and continue as you were, with the benefit of your battery life is not reduced. I always use suspend to disk, because I always have certain programs running and it is nice to just switch my laptop on and have it all set up as I want, without having to load everything again.

yeah I guess I'm looking for Suspend to RAM then...also cus my laptop has 1 gig of RAM and I never really use it (or abuse it should I say)

Concerning the modules not unloading - I never got my ipw3945 module to unload with rmmod. But it works using | Code: | | modprobe -r ipw3945 |
. So if this is the same for your ipw you could try:
| Code: |
OnSuspend 20 modprobe -r ipwXXXX
|
in your hibernate.conf |

suspend2 saves the whole ram (incl. disk cache) by default, which results in a 100% state-restored 100% responsive system.
if you want do discard some cache, try ImageSizeLimit setting, and set it to nocache. this way I hibernate in 3sec, resume in 2.

This is really a great tip - maybe you want to put it into the wiki or so? Makes everyday resume and suspend much more fun  |
