Hello; O.K. I applied the patch. after rebooting I was still seeing
this message, also I noticed HAL daemon was taking longer
to start. when unplugging the A/C adapter with pommed the screen
wouldn't dim, and under dmesg nothing about the battery.
when unplugging and plugging in. also with suspend the screen took
longer than normal to recover. So feeling uncomfortable
with how this patch was causing the system to react, I reverted back
just to be safe. After reverting it took a few reboots to bring the
battery
back to a good state. I'm not sure if this was because of ec.c or not.
Now before this patch The only chage that I had done was change 5 to
20,
after a few day's I did notice this message to dissipate. Maybe this
is just something with a macbook pro, and not other computers, with
this patch.
regards;
