As this says, it is a BIOS bug, which means your hardware is broken, not the kernel.

Changed in linux-source-2.6.22:
status: Unconfirmed → Rejected

But I don't report this error in Feisty bootstrap! I obtain this result when I use a Gutsy Live CD only.

I'm using : ~$ uname -a
Linux NEANT 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux

I have included the DSDT.aml in the initrd following the HOWTO :
https://help.ubuntu.com/community/ACPIBattery

The dsdt compilation shows no error and no warning.
I have just dpkg-reconfigure the kernel, including the DSDT.aml file in the directory : /etc/initramfs-tools/.

I always get the same lines in dmesg...

I'll try to verify how it was under Feisty, but I didn't have any problem with power management with the previous kernel (2.6.20 if I remember)

So since there is no bug in the dsdt compilation, couln't it be a kernel bug?
