I don't know if this is related, but on my Thinkpad R51, and 2.6.12-1.1447_FC4 kernel, I see similar messages in the dmesg attachment that mitr is encountering: ACPI-0145: *** Error: Invalid owner_id: 00 ACPI-0145: *** Error: Invalid owner_id: 00 ACPI-0145: *** Error: Invalid owner_id: 00 It appears to grow, and wasn't present in the last updates-released kernel for FC-4.
Ok, scracth comment #3. I get exactly a similar response as mitr is getting only _after_ I close the LID, and the machine isn't set to sleep (but the screen blanks). And consequently, battery status can't be read, and the GNOME display shows "System is running on battery power. Battery status unknown" even when plugged in to AC power. This was not an issue in 1398, but only in the new 1447.
Could you please try patch in #166816?
