Greetings All,
I'm struggling with TuxOnIce / Hibernate / Suspend2. Everything works fine except that the system does not power itself off at the end.
/sbin/poweroff (/sbin/halt) works fine to shut the power off, but the hibernate script cannot do it! I've had this installed through several kernel versions (2.6.23, when it was a patch, through 2.6.27). It's always had the same problem. Sometimes it's had additional problems as well.
I would think that the answer would be to edit /etc/hibernate/suspend2.conf, and set:
I've also tried:
Both yeild the same result. The discs spin down, drivers are unloaded, everything works fine, except the system does not shut it's own power off. I suppose I should just be happy that the system wakes up fine.
Any idea how I might remedy this situation?
Here is some relevant data:
| Code: |
-> uname -a
Linux vera 2.6.27-gentoo-r7 #5 SMP PREEMPT Fri Jan 16 21:12:21 CET 2009 i686 AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ AuthenticAMD GNU/Linux
-> equery list hibernate-script
[I--] [ ] sys-power/hibernate-script-1.97-r4 (0)
-> equery list acpi
[I--] [ ] sys-power/acpi-0.06-r5 (0)
[I--] [ ] sys-power/acpid-1.0.6-r1 (0)
-> rc-update show | grep acpi
acpid | default
|
Thanks in advance,
Bryant

Finally!
This is the fix:
| Code: |
echo shutdown > /sys/power/disk
|
I wish I could have that 2 hours of my life back. I wasted hours digging through the sys-power/hibernate-script; the config files, the man pages and the source code! In the end, I found the answer in the kernel docs (/usr/src/linux/Documentation/power/interface.txt). It would be extremely useful if this interface was exposed through the hibernate-script conf files.
Since I spent so damn long with this, I'll provide an excessive bit of background:
Here is the previous setting:
| Code: |
cat /sys/power/disk
[platform] test testproc shutdown reboot
|
Maybe there's a bios config or a bios upgrade that I could do so that the "platform" setting would poweroff the box. I don't know.
Here's the code from hibernate-script that controls this. The installed location is: /usr/share/hibernate/scriptlets.d/sysfs_power_state
| Code: |
DoSysfsPowerStateSuspend() {
if [ -z "$SYSFS_POWER_STATE_NO_SUSPEND" ] ; then
vecho 1 "$EXE: Activating sysfs power state $USING_SYSFS_POWER_STATE ..."
[ -n "$SYSFS_POWER_STATE_POWERDOWN_METHOD" ] && \
[ -f "$SYSFS_POWERDOWN_METHOD_FILE" ] && \
/bin/echo $SYSFS_POWER_STATE_POWERDOWN_METHOD > $SYSFS_POWERDOWN_METHOD_FILE
/bin/echo -n $USING_SYSFS_POWER_STATE > $SYSFS_POWER_STATE_FILE
else
vecho 1 "$EXE: Not actually suspending (--no-suspend given)"
fi
return 0
}
|
I would expect that if:
is set in /etc/hibernate/suspend2.conf
then /sbin/hibernate should do a "halt / poweroff" command instead of using acpi via /sys/power
However, that's not the case.
I know, I know...I should be taking this up with the TuxOnIce guys. They're next...
Final note: I see that /sys/power/disk is reset to [platform] after a couple of reboots. I need to find the place to remove the code that resets that, or to hard-code that [shutdown] setting somewhere.... |
