First sorry for using the mailing list and not bug-report but i didn't find it would fit as the debian-cd package bug. I'd just wanted you to take a glance at [http://bugzilla.kernel.org/show_bug.cgi?id=13431] and hope next image would get this fixed. I had to boot without acpi to get debian installed and blacklist the module,and 2.6.30 solved my problems. Thank you for your time, Luis.
