* Tue Mar 30 2010 Chuck Ebbert <cebbert>
 - ACPI EC fixes pending upstream: 
    acpi-ec-add-delay-before-write.patch
    acpi-ec-allow-multibyte-access-to-ec.patch

Ubuntu is having the same problem

*** Bug 581882 has been marked as a duplicate of this bug. ***

Should be fixed in kernel-2.6.33.2-44.fc13

Attaching the full panic I'm seeing for future searching.

I can confirm that the issue is resolved with 2.6.33.2-46.fc13.i686

It's also fixed for me with kernel-PAE-2.6.33.2-46.fc13.i686 on a ThinkPad x301.

Fixes it for me too in here.

Closing this as it's fixed for me, and several previous reporters and available in Fedora 13.

kernel-2.6.33.2-57.fc13 has been submitted as an update for Fedora 13.
http://admin.fedoraproject.org/updates/kernel-2.6.33.2-57.fc13

kernel-2.6.33.2-57.fc13 has been pushed to the Fedora 13 stable repository.  If problems still persist, please make note of it in this bug report.

I'm using Fedora 13 with kernel 2.6.33.5-112 on an Asus F81s Notebook and it's having the same problem, it can not boot with acpi enabled.
