Ubuntu on Dell Inspiron 1501

I read some post on the net explaining that with kernel version < 2.6.19 the hibernate and suspend may not work with the AHCI SATA. It may not work beause the AHCI was not restore after the suspend...

With the default Ubuntu 6.10 kernel (2.6.17-10), the suspend was not working.

So I upgrade to kernel 2.6.20:

This is the step:
cd /usr/src
sudo wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2
sudo tar xjf linux-2.6.20.tar.bz2
cd linux-2.6.20
cp /boot/config-2.6.17-10-generic .config
make oldconfig
make
make modules_install install
cd /boot/
mkinitramfs -o initrd.img-2.6.20 2.6.20

Then I add the following grub entry in /boot/grub/menu.lst:
title Ubuntu, kernel 2.6.20
root (hd0,4)
kernel /boot/vmlinuz-2.6.20 root=/dev/sda5 ro quiet pci=nomsi
initrd /boot/initrd.img-2.6.20
quiet
savedefault
boot


Note: With kernel 2.6.17-10, I was using the acpi=force irqpoll kernel option, but the system hang when I used it with 2.6.20, do I remove it.

Then the hibernate and suspend work like a charm...

Enjoy,
