can't shut down

can't shut down

[majie]

Hi all,

I'm using Linux kernel 2.6.21.5-smp(Slackware 12). I experience an
error when I turn off my computer. It doesn't turn off itself (maybe
called going into G2/S5 Soft Off in the specification) after printing
a message "acpi_power_off called". I have to press the power button
for several seconds to turn it off. I think the CPUs may be running in
full speed because I hear my fan running in high speed.

I tried to find out the problem by adding some printk()'s to the
function acpi_enter_sleep_state()(in
linux-2.6.21.5\drivers\acpi\hardware\hwsleep.c). And It shows that it
runs into the final do-while loop in the function and doing an
infinite loop. Maybe this is why my CPUs are running in full speed.

I don't have the ability to debug the kernel. So this is the only
information I can provide about the code. If you want me to post my
hardware spec or anything else, I'm very glad to, but please tell me
which command and arguments should I use to get the info.

I have tried the kernel options, but they don't work for me. My laptop
can shut down flawlessly when using windows xp.

By the way, It's a linux distribution independent problem because I
also experienced it in kubuntu 7.10.

I'm truly grateful for your help.
Thank you very much.

Best regards,

Will you please attach the output of acpidump?
The latest dump tool (20070116) can be found in 
http://www.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/

Hi Yakui,
Do you receive my email I sent to you on April 19 ? I'm still unable to 
have the 2.6.25-rc9 kernel boot and run. I can't make a valid initrd to 
boot the kernel. I've spend the whole weekend to solve the problem. But 
I've no idea why it can mount my real root filesystem.

So I can't test the 2.6.25-rc9 kernel in normal mode. I want to shutdown 
the computer using busybox's poweroff in the initrd before the real root 
filesystem being mounted. Is this approach equal to the "normal" shutdown?

Sorry for causing the trouble to you.
Thank you.

Sorry for the no response.
IMO the problem is related to the kernel config. For example: the SATA
driver should be built into kernel. (If not, OS can't find the root
filesystem).
Please do it again as listed in the following:(Pay attention to the
kernel configuration).
a. make bzImage; make modules;
b. make modules_install; make install;

Hi, Yakui

2.6.25-rc9 kernel successfully runs on my computer. But the bad news is 
that this kernel can't shut down my computer too. Can you fix this 
problem in a newer kernel? Thanks.

And my dmesg output is here.

Hi Sergio,

I tried 2.6.25-rc9 as Zhao Yakui told me to. But it doesn't work too.

Thanks for the information.
