I have the same problem.
Can reproduce any time, all you have to do is boot up:

Here is the trace from dmesg:

Comment 2 Einer Petersen 2009-11-29 22:58:25 UTC 
Ok,

This bug does not rear its head after every boot.

I would have attached the complete output from acpidump and dmesg, error vs no error, but not way to do from what I can see. So, here are the diffs at least.
################################################################################
Here is the diff in the output from dmesg and acpidump after a reboot that produces the error and one without the error:

Ok,

This bug does not rear its head after every boot.

I would have attached the complete output from acpidump and dmesg, error vs no error, but not way to do from what I can see. So, here are the diffs at least.
################################################################################
Here is the diff in the output from dmesg and acpidump after a reboot that produces the error and one without the error:

one other comment .... looks like this is happening on both X86_64 and i686 loads.
Comment 5 Bug Zapper 2010-11-04 05:38:47 UTC 
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Comment 6 Bug Zapper 2010-12-04 02:55:52 UTC 
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
Comment 7 Steven Ellis 2011-02-10 21:23:12 UTC 
This bug is still present in Fedora 14.
