what's looking badly is this:

ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [\_S1_]
(20131218/hwxface-580)
ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [\_S2_]
(20131218/hwxface-580)

and this:

acpi PNP0A08:00: _OSC: OS supports [ASPM ClockPM Segments MSI]
\_SB_.PCI0:_OSC invalid UUID
_OSC request data:1 1e 0
acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM

but these messages are not new.
