Hi:

 I get the following error warning sometimes. Have I failed to configure something ?


login: May 31 23:02:38 notebook login: ROOT LOGIN (root) ON ttyv2
    ACPI-0502: *** Error: Handler for [EmbeddedControl] returned AE_NO_HARDWARE_
RESPONSE
    ACPI-1303: *** Error: Method execution failed [\_TZ_.THRM._TMP] (Node 0xc43e
fca0), AE_NO_HARDWARE_RESPONSE

The relevant information from dmesg is:

pcibios: BIOS version 2.10
