Pm-suspend problem on laptop

wizulis · 2010-04-22 15:11:49

So, I have an Emachine E725. It has been a real pain even in windows, but, most of stuff i have gotten working with an option here, option there etc( like adding acpi_osi="Linux" to boot parameters fixed few display brightness problems ) .

But now it's time to get the suspend working,
when I do: #sudo pm-suspend it goes in a sleep and everything is OK, but when i resume (by pressing space or whatever) it starts, i see desktop, the opened programs, but after ~ 1 sec, an error is thrown about Network manager not being able to find some resources (sometimes the a gray box has squares where text should be and only button, to close it). After that, the system basically stops working. After doing a double-tab, only about 100 commands (as root)are listed, some of them aren't even commands ( and there is no shutdown or reboot or any available).
From /var/log/pm-suspend.log :

Thu Apr 22 17:43:10 EEST 2010: performing suspend

Tried to just disable the 75 hook, but did not change anything. Same thing is with pm-hibernate.

Does anyone has any ideas what could be the problem or where to find any other stuff to debug problem.

p.s. the /var/log/everything.log has nothing about performing suspend, the log stops and starts again with the boot process, so after pm-suspend is executed, nothing is written to it until the hard reboot, but i found a strange errors in boot process from "load-modules.sh" like:

Apr 22 17:44:25 wizulis load-modules.sh: 'acpi:PNP0C02:' is not a valid module or alias name
Apr 22 17:44:25 wizulis load-modules.sh: 'platform:iTCO_wdt' is not a valid module or alias name
Apr 22 17:44:25 wizulis load-modules.sh: 'acpi:PNP0200:' is not a valid module or alias name
Apr 22 17:44:25 wizulis load-modules.sh: 'wmi:6AF4F258-B401-42FD-BE91-3D4AC2D7C0D3' is not a valid module or alias name

p.p.s Sorry for any grammar mistakes, its been a long time since i have wrote anything in English

*edited some mistakes

Hello wizulis,

use the debugging routine as described here.

You can also use "PM_DEBUG=true pm-suspend" to get more, hopefully useful, information out of pm-suspend. Otherwise use s2r as described in the first link.

Thanks for answer demian,
tried all tests described, none off them returned an error, but when i tried to hibernate using
# echo platform (or reboot or shutdown) > /sys/power/disk
# echo disk > /sys/power/state
The wakeup process still failed..

Did a boot with init=/bin/bash and did and
#/usr/sbin/s2ram

it suspended, but on wakeup a 3 error infinite cycle started .. it said ( not sure of the order, or which of them was first)
ata1: SError : {DevExch}
ata2: exception Emask 0x10 SAct 0x0 SErr 0x4000000
ata2: irq_stat _0x00000040, connection status changed

Edit:

tried to boot with irqpoll and acpi=noirq options .. in /bin/bash nothing changed, but after booting with those options in normal system, issuing s2ram -f right after boot, recived an "Segmentation fault" error.

Okay, so that didn't really help. IRQ error could be any device.
Judging from your initial description though the culprit might be ethernet, wifi or wlan.
Here's what i would do next:

1) Blacklist the corresponding kernel modules. Find out by typing lspci -k. Besides the modules for connection devices like ethernet, wifi or wlan it might be also worth a try to disable any other non-critical hardware module like finger print reader, sd card reader and so on. Also disable ipv6. Don't disable modules you can't identify though.
2) If blacklisting (or banging) in rc.conf doesn't work you could search the BIOS for an option to disable I/O-port access to hardware. If there is no such option you could still try to disable modules at boot time via modprobe.conf
3) Try different DEs/WMs. I don't know why but I've heard from several places that suspend works in one DE but not the other.
4) This might not be related at all, but try suspending without KMS or X. I think it'll suffice if you just append i915.modeset=0 3 to your kernel line in menu.lst.

Good luck.

Regards,
demian

experimenting with your suggested problem solvers, on wake i noticed an error, why my root is being mounted as read only it said:

ext4_journal_start_sb: Detected aborted journal

And then i mounts the system as read only and throws out errors about ext 4 file system at random time intervals. After a bit of googling, most of threads about this problem suggested a hard drive going bad, but as this happens only on suspend/wake, could there be a conflict between hardware, ext4 and suspend ? Is it possible?

As for now, i have tried blacklisting wl (broadcom wireless cards) and atl1c ( atheros wired card) drivers, and ipv6 , suspend without X and suspend in xfce,gnome and awesome. I have laptop with pretty empty BIOS so i cant disable anything in it, but i checked the manufacturers web site, there are ~ 10 updates from my version (i have 1.03, newest is 3.07), but as there is no release informations available, so i dont know if bios update is worth the risk, as i can update it through windows only i think.( i bought my laptop in Latvia, and so US costumer service just refused to give out any information regarding bios updates (ehh) )

I have the same laptop, how did you get the laptop to boot into arch without getting a black screen or using nomodeset in the /grub/menu.lst?
what graphics drivers do you use?

Arch Linux
