Summary: HP dv2910us EC errors
Kernel Version: 2.6.31-rc8
My DSDT has errors in it that can be fixed, but runtime DSDT replacement is no
The basic problem is the following message:
[ 7756.412107] ACPI: EC: missing confirmations, switch off interrupt mode.
Followed 500ms afterwards by
[ 7756.913187] ACPI Exception: AE_TIME, Returned by Handler for
[EmbeddedControl] 20090521 evregion-424
[ 7756.913216] ACPI Error (psparse-0537): Method parse/execution failed
[\_TZ_.TZS0._TMP] (Node ffff88013ba2a520), AE_TIME
The fan control of the laptop sometimes acts berserk, spinning up then down
again repeatedly. Other than that, I guess the only problem is the
(theoretical) CPU usage of polling mode.
