ACPI Exception (evregion-0424): AE_TIME, Returned by Handler for [Embed=
dedControl] [20060707]
ACPI Exception (dswexec-0458): AE_TIME, While resolving operands for [O=
pcodeName unavailable] [2006070
7]
ACPI Error (psparse-0537): Method parse/execution failed [\_TZ_.THRM._T=
MP] (Node ffff810002032d10), AE
_TIME

OK, I don't get the WARN_ON when these happen, so it's got to be one of=
 the
other EC updates.

It'd be nice if this were easily reproducible ...
