Mario,

Yes, it does.

Is there any estimates on when the patch will be merged into mainline? I want 
to put something into my distribution bug tracker, but it's unlikely they will 
use this patch before its stabilization.

Yes, around a month ago (the firmware option). Still, there is a time frame 
between the firmware update and the problem surfacing. As I said it was 
eliminated by switching POST/fastboot to the thorough mode. I just have tried 
to reproduce the problem with previous settings, but with no success. So, that 
is (in a way) closed, but I have no idea what it was about.

Thank you.
