Introduction

ACPI support is tough to get right, so we expect to frequently see problems there. See [http://www.acpi.info/ www.acpi.info] and [http://en.wikipedia.org/wiki/Acpi Wikipedia] for background information.

How to file

TBD.

Debugging procedure

When debugging ACPI problems, ask for the following information:

• Ask them if their BIOS is up to date.
• Output of 'uname -a'
• Output of 'sudo lspci -vv'
• Output of 'sudo lspci -vvn'
• Output of 'sudo dmidecode'
• Ask the user to try to hibernate/suspend and then restart the system and attach /var/log/kern.log.0

Such bugs should be against linux-source-# where number is the specific kernel version. For example, the correct package in Malone for Edgy is linux-source-2.6.17 and for Feisty it is linux-source-2.6.20.
