Hi,
I cannot have suspend and hibernate working on a Samsung NC10 (netbook) running CentOS 5.4 i386.
When I try suspending/hibernating the screen becomes black (with a few logs, like "shrinking memory" for hibernate) and then the computer hangs and I have to force a shutdown with the power button.
This wiki page seems to say that it should work out of the box: http://wiki.centos.org/HowTos/Laptops/Samsung/NC10
I tried to add the kernel arguments described here, to no avail: http://lists.centos.org/pipermail/centos/2007-June/040633.html
Anyhow the problems doesn't seem to be the resume but rather getting into the suspended/hibernated state.
When I log after a failed attempt, GNOME shows a popup saying that apparently we failed to recover from a suspend/hibernate state and that this may be a driver problem.
A few more information about my settings which may be useful: - the root filesystem is installed on an LVM - I use the NetworkManager and not the network service - I disabled bluetooth (in order to remove all unused devices that may impact this problem) - [mbaudier@localhost ~]$ lshal | grep suspen org.freedesktop.Hal.Device.SystemPowerManagement.method_execpaths = {'hal-system-power-suspend', 'hal-system-power-suspend-clear-error', 'hal-system-power-hibernate', 'hal-system-power-hibernate-clear-error', 'hal-system-power-shutdown', 'hal-system-power-reboot', 'hal-system-power-set-power-save'} (string list) power_management.can_suspend_to_disk = true (bool) power_management.can_suspend_to_ram = true (bool) power_management.can_suspend = true (bool)
Thanks in advance if somebody can tell me how I can analyse further / solve this.
Cheers,
Mathieu

I am using my own sky2 ethernet driver(since 5.3)/ath_pci wifi driver: [tru@snoopy ~]$ modinfo sky2 filename: /lib/modules/2.6.18-164.9.1.el5/weak-updates/sky2/sky2.ko version: 1.18 license: GPL author: Stephen Hemminger shemminger@linux-foundation.org description: Marvell Yukon 2 Gigabit Ethernet driver srcversion: 4D063BC8FAD26BE4B493E77 ... [tru@snoopy ~]$ modinfo ath_pci filename: /lib/modules/2.6.18-164.9.1.el5/net/ath_pci.ko license: Dual BSD/GPL version: svn r3879 description: Support for Atheros 802.11 wireless LAN cards. author: Errno Consulting, Sam Leffler srcversion: 53828DCE2B2CEC52C9E9103 ... Which requires a small hack in the pm config file: [tru@snoopy ~]$ cat /etc/pm/config.d/ath_pci SUSPEND_MODULES=ath_pci RESUME_MODULES=ath_pci
Maybe you need to add the sky2 driver to the list.
I haven't tried the newer sky2 driver from the 5.4 kernel serie, ymmv.
