ACPI battery exception

Description of problem:
Right after boot 'dmesg' shows ACPI exceptions already. And more and more are added. After some undefined period of time (say about 10 minutes) the system hangs with a kernel oops (probably because of this, haven't been able to copy this exact error yet). The above url shows dmesg output.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Just boot.
- Battery is not reckognized correctly.
- System hangs (I'm forced to power off).
My Notebook is an Acer Aspire 1640Z.
It worked fine with Fedora Core 6 (but then I had some other problems, which are fixed now :)
There doesn't seem to be any link to dmesg output in the bug report.
Can we get the exact error messages/ oops report?
Sorry, I hid it in the additional bug information (the URL points to it).
I provided three files now:
- One immediately after booting: (has only few errors at the end)
- One after some work: (same as in additional bug information)
- One immediately after booting with acpi=off:
I wouldn't know how to copy/paste the final bug, I tried to write something
down, if you need more information, I'll do it in more detail. The beginning
might be chopped of, I could not scroll further up.
Thanks very much for your time! Jonne.

Same problem is still existent with this kernel
Really hope somebody has a workaround or fix for this.
Something changed with this kernel: (though I hope it's not only a change in

I still get these lines in 'dmesg'

But they're *not* anymore followed by this:

Battery is still not working correctly.
Here is some (hopefully usuable) additional info:

I'm afraid it could also be some hardware problem that occurred when upgrading
to F7. With the Knoppix dvd (KNOPPIX_V5.1.1DVD-2007-01-04-EN with 2.6.x kernel)
the same problem arises.
Here's dmesg output:
Anybody knows what I can do to be sure? Should I replace the battery??
Sorry, typo in the URL, should have been
in the previous comment.
Same problem occurred with replaced battery. It is a software bug, right?
I know have kernel-2.6.21-1.3194.fc7 and it still shows the battery exception, see:
any advice on what I can try?
I was able to replace the battery with someone elses and that solved the
problem. Hence, I must conclude it's very likely to be hardware failure.
The battery exception was a good indication for that, so I guess I should not
have filed this bug report (although such a thing is frustrating and hard to
check or be sure). So, thanks everybody for helping and I'll close this bug.
