Subject[Bug 1137] New: non fatal ACPI errors on boot
http://bugme.osdl.org/show_bug.cgi?id=1137

Summary: non fatal ACPI errors on boot
Kernel Version: 2.6.0-test2-mm4
Status: NEW
Severity: low
Owner: len.brown@intel.com

The following ACPI errors on boot. System boots fine and I have not noticed any
regressions or loss of functionality. ACPI does not detect power button events
though.
