Hi Fabio,

There are no bad news in seeing the message, as I tried to say several
times in bug report already. We can't fix the hardware.
We only could detect hardware flaw, report it (the message), and try to
workaround it.
So the bad news would be that our workaround causes some unwanted behavior to
other features of notebook -- keyboard, special keys, battery & AC status reports, etc.
If no such problems were noticed -- there is no bug, and there is no problem.

Regards,
Alex.
