commit 14acdde6e527950f66c084dbf19bad6fbfcaeedc upstream.

The newer single chip hardware family of chipsets have not been
experiencing issues with power saving set by default with recent
fixes merged (even into stable). The remaining issues are only
reported with AR5416 and since enabling PS by default can increase
power savings considerably best to take advantage of that feature
as this has been tested properly.

I havent had any issues lately. But that said Ive moved on to
2.6.33, 2.6.34 which seems to work fine. Believe you set
to disabled by default on those?

/Kristoffer


just tried to add this patch to the latest HEAD, but realized
ath_set_hw_capab is missing(or I cant seem to grep it)
if you have a patch for the latest tree let me know I can see if I'm hitting
anything like before.

The patch would already be merged since 2.6.33.y, this patch is a
backport for 2.6.32.y. I just hadn't had time to backport it yet,
until today.

so its already in there then..

Right

if that's the case then the system runs
good with powersave on then..

Did you read the patch by chance? It only enables power save for
non-AR5416 hardware. What do you have?

     Luis


mine is the AR5008

Ok I should say, all AR5008 and AR9001 family chipsets have
power save disabled still. Only AR9002 and up have it enabled
now. The patch was doing the same for 2.6.32.

    Luis


o.k. I have not tried what powersave does since the last time I looked
into this bug(if I remember 2.6.31/2 or so) I can manually
turn it on with iwconfig and see..

Thanks but no need, its not the purpose of the patch.

   Luis


o.k.
