Description Ryan Underwood 2009-09-04 03:41:43 UTC 
My DSDT has errors in it that can be fixed, but runtime DSDT replacement is no longer available.

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.

Please check if patch in http://bugzilla.kernel.org/attachment.cgi?id=22911
helps.
Comment 13 Ryan Underwood 2009-09-04 12:55:26 UTC 
No, this problem occurs with or without that patch.  (It was also my bug)
Comment 14 ykzhao 2009-09-29 05:53:47 UTC 
this issue is also related with EC AE_TIME.
So this bug will be marked as the dup of bug 13055.
