ACPI EC warnings

ACPI EC warnings

[Ismail Donmez]

Hi,

With the recent ACPI merge I get this in dmesg:

ACPI: EC: evaluating _Q60
ACPI: EC: evaluating _Q60
ACPI: EC: evaluating _Q60
[...]

and similar warnings. Also I am not completely sure but sound skips when I get 
this warning. Anyone experiencing the same problem? Also why does ACPI is 
polluting dmesg like this?

Regards,
ismail

Patch looks nice, btw do you notice any skippy behaviour? i.e sound skips when 
I get this warning or something else is broken and I blame ACPI because its 
flooding dmesg =)

But LKML didn't like gmail's HTML so here is it again. Hopefully this 
one will pass.

No, in my case I just get the message: ACPI: EC: evaluating _Q20

I happen to have at the moment some other debugging printk, flooding
my logs, and sound doesn't skip either :-) Asus V6VA - Pentium-M 2GHz here.

I think this one didn't pass either :-/

Yeah the warning seems unrelated to skips.
