Slackware 12.2 won't be powered off after recompiling kernel

lchxr · 04-20-2009, 11:46 AM

I want to recompile the kernel to enable high-resolution timer. What I did are

Code:

$ su
# cd /usr/src/linux
# make mrproper
# cp /boot/config-generic-smp-2.6.27.7-smp .config
# make menuconfig #     <---enable high-resolution timer and filesystems here
# make 
# make modules_install
# cp arch/i386/boot/bzImage /boot/bzImage-2.6.27.7-smp
# vi /etc/lilo.conf #    <---change image here
# lilo -v
# reboot

Everything went well after recompiling the kernel except for 'shutdown'. When I type shutdown -h now, it went through the normal shutdown process. However, it stops at some point (see below) and the machine is dead. I need to power off by pressing the button. One more thing to mention: reboot works perfectly.

Code:

...
/dev/sda1 unmount
/dev/sda8 unmount
/dev/sda7 unmount
/dev/sda6 unmount
/dev/sda5 unmount
usbfs unmount
/dev/root unmount
Remounting root filesystem read-only.
/dev/sda1 on / type ext3 (ro)

The machine stops here.

It seems that ACPI caused the problem. Does anyone tell me what options I need to setup?

Was ACPI compiled into the kernel, or as a module? Or was it even compiled at all? Check your kernel configuration, and also try lsmod to see if ACPI is loaded.

Hello,

Check if /etc/rc.d/rc.acpid is executable? If not run as root:

Code:

chmod +x /etc/rc.d/rc.acpid

Yes, ACPI was compiled into kernel and /etc/rc.d/rc.acpid is executable.

Try to force acpi at boot time by adding the following to /etc/lilo.conf:

Code:

append=" acpi=force"

Example of where to put the additional line:

Code:

image=/boot/vmlinuz
label="linux"
root=/dev/hda5
initrd=/boot/initrd.img
append=" acpi=force"

Do not forget to run /sbin/lilo after modifying the lilo.conf file.

Problem updates.

In kernel-2.6.27.7 shipped with Slackware 12.2, if the high-resolution-timer is disabled, everything goes well. However, if enabled,

Code:

CONFIG_TICK_ONESHOT=y
# CONFIG_NO_HZ is not set
CONFIG_HIGH_RES_TIMERS=y

the power-off process would stop at some point. This shows that high-resolution-timer conflicts with something else.
