Dell Inspiron 5100

[Filippo Forti]

Hello,

Today I updated bios to version A32 on my inspiron 5100.
As a result, I often get messages similar to these:

ACPI-0501: *** Error: Handler for [EmbeddedControl] returned
AE_NO_HARDWARE_RESPONSE

ACPI-1304: *** Error: Method execution failed [\\_TZ_.THRM._TMP]
(Node 0xc226ea60), AE_NO_HARDWARE_RESPONSE

I'm not running on a modified dsdt at the moment.
S1 is the only sleep state which seems to work, although the bios claims
itself as "S4 capable". Attempting to enter S3 or S3 causes the Inspiron
to reboot. 

Attempting to disassemble and compile the DSDT gives several warnings:

Has anyone experienced or solved such a problem?
