Description Ralf Corsepius 2008-10-20 22:38:08 EDT
Description of problem:
I am observing this:

# grep ACPI: /var/log/dmesg
ACPI: EC: non-query interrupt received, switching to interrupt mode
ACPI: EC: GPE storm detected, disabling EC GPE
ACPI: EC: GPE = 0x17, I/O: command/status = 0x66, data = 0x62
ACPI: EC: driver started in poll mode

Version-Release number of selected component (if applicable):
Current (2008-10-21) rawhide: kernel-

How reproducible:

Additional info:
* I read http://bugzilla.kernel.org/show_bug.cgi?id=10724
but this didn't answer much to me.
* The machine exposing this issue is a Medion E1210, an Atom N270 based netbook, an MSI Wind variant.

The message is pretty harmless - it simply indicates that your embedded controller has been switched into polled mode. This code is currently being rewritten and the message should disappear in 2.6.28 or 2.6.29.

If you say so - Let's keep fingers crossed ;)
