Hi,
In 3.1.0-rc5-dirty the following warning appeared in dmesg:
[ 249.506212] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20110623/evregion-478)
[ 249.506387] ACPI Error: Method parse/execution failed [\_SB_.PCI0.SBRG.EC0_.RCTP] (Node ee96daf0), AE_TIME (20110623/psparse-536)
[ 249.506636] ACPI Error: Method parse/execution failed [\_TZ_.RTMP] (Node eeb85000), AE_TIME (20110623/psparse-536)

[ 249.511953] Thermal: failed to read out thermal zone 0
Shortly followed by a bunch of kmemleak warnings (the initial trigger
has not been reproducible though):
