Hi, Rafael,
 
Yes. I tested without reverting the patch that caused failure on E6410 (with same AHCI controller), The system is Ubuntu 11.04 with default 2.6.39-rc6 kernel (guess this should be same kernel as yours before reverting the patch).
 
My system worked well with AC power cable plugging in and out at boot time, at runtime, and during "dd if=/dev/sda5 of=/dev/null ..".
 
The config file I mentioned is those under /etc/ or other directories that is used to control the power management.
 
Did you test my patch? What it the result?
 
Thanks,
Jian

OK, do I think correctly you tested without the patch you sent previously?

I'm not sure what you mean.  The kernel .config?
