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.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/Thanks.

Here it is. Thanks. ------ Regards, majie
