suspend and resume only works with fallback image

mehldutt · 2009-03-01 10:15:51

I get a black screen on suspend and resume with pm-utils after I boot with main kernel image.

However, fallback image works fine.

I'd like to figure out what's missing in the main kernel image.

lsmod looks the same with both images.

How should I proceed?

Try `echo mem > /sys/power/state' and see if you can resume. I also haven't been able to resume since yesterday, both from pm-suspend and from `echo mem > /sys/power/state'.

same result,
`echo mem > /sys/power/state' only works with fallback image.

maybe this helps:

mkinitcpio.conf

MODULES=""
BINARIES=""
FILES=""
HOOKS="base udev autodetect pata scsi sata resume filesystems"

/var/log/pacman.log revealed that I upgraded acpi yesterday. Run `pacman -Q acpi'. If it says you're using acpi 1.3, try downgrading to 1.2 (`pacman -U http://ftp.icm.edu.pl/pub/Linux/sunsite/distributions/archlinux/extra/os/i686/acpi-1.2-1-i686.pkg.tar.gz'). It fixed the issue for me.

Edit: The problem probably lies upstream with acpi, and someone (I'm quite busy right now) ought to file a bug report...

you are my hero...before I read this post I could never resume my laptop running Arch no matter what quirks I tried. That's actually why I've been running Fedora - resume worked. In fact, resume works on every other distro I've tried.

As far as an ACPI update being to blame, I've had problems resuming in Arch for over a year, although I can't go back in time to try the fallback and see if it works

When I get some spare time, I'll copy the mkinitcpio config for fallback to the main config and start removing modules / hooks to see which one breaks it

EDIT: /etc/mkinitcpio.d/kernel26.fallback no longer exists - it just uses autodetect. Also, the loaded modules are the same no matter which image was used to boot, so I'm stumped. Maybe somebody who knows more about that mkinitcpio does can shed some light
