[PATCH] EC Burst

[PATCH] EC Burst

[Johannes Engel]

Hi Len!

Asking the developers at SuSE about my problem they sent me to you. So
here I am. :)
With the standard kernel my laptop delays the recognition of ACPI events
seemingly using a queue of length 8. I found a patch some weeks ago
which corrects that problem. If it can help others, too, maybe you can
put it to the mainline. You will find details under
http://bugzilla.kernel.org/show_bug.cgi?id=5713.

Greetings, Johannes

FWIW, we've had a number of Fedora users reporting similar problems
(Things like battery status applets not updating and the like).

Though we've got the upstream default of ec burst being disabled there.

RE: [PATCH] EC Burst

[Brown, Len]

This should be addressed already
by the fix to 4980 and the enabling of EC interrupt mode by default.
BTW. it is now called "ec_intr" rather than "ec_burst".

This fix has been in the ACPI git tree since Monday
and should appear in the next mm tree.

cheers,
