Re: acpi not accepting command

Hi!
I'm running FC3 (2.6.10-1.766_FC3smp) on a HP ZD7000 laptop (2G RAM). In
grub.conf I set up acpi=on apm=off and my sleep.sh is as shown below.
Here is my sleep.sh:
#!/bin/sh
# pre-suspend:
oldvt=$(fgconsole)
chvt 1
/sbin/modprobe -r uhci_hcd
/sbin/modprobe -r ehci_hcd
echo mem > /sys/power/state
# on wake-up:
video_post
/sbin/modprobe uhci_hcd
/sbin/modprobe ehci_hcd
chvt $oldvt
The script is run when I close the lid. So, I close the lid and the laptop
seems to go into sleep, but wakes up right away. I finally tracked down the
problem to this command:
echo mem > /sys/power/state
For example, if I type in a terminal as root: echo mem > /sys/power/state
nothing happens. It takes the command in very quicky and doesn't send any
error, but it also doesn't do anything either. Just like if I have pressed
the RETURN key with no command before it.
It seems like I'm missing the proper ACPI support in the kernel, but this
kernel comes straight from Fedora and I have not changed anything in the
kernel. I have a HT CPU so I'm using the smp that needs ACPI and it
recognizes that ACPI is there with no errors. Also, the LID triggers the
sleep.sh script as it should. So, is there somewhere another switch for ACPI?
What am I missing?
(1) Is acpid running?
(2) People have reported the problem you are seeing with immediate
wakeups. In my script, the suspend is initiated by
echo 3 > /proc/acpi/sleep
That is supposed to be a workaround for this problem.
Thanks,
