Reassigning to correct component
Comment 3 Zdenek Prikryl 2009-04-21 10:03:56 EDT
In dmesg output there is this warning:

ACPI Warning (nspredef-0940): \_SB_.BAT0._BIF: Return Package type mismatch at index 9 - found Integer, expected String/Buffer [20081204]

It seems that this is kernel bug, so reassigning to kernel. Similar bug is discussed here: http://bugzilla.kernel.org/show_bug.cgi?id=11822.

The mentioned bug seems to be related. But it should have been fixed in  2.6.28-rc6-git2 upstream ...
Comment 5 Bug Zapper 2009-06-09 10:18:31 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

It seems as if this fixed in the current rawhide and can be closed.
