Sorry I for my going AWOL...

I've spending most of my time out of my country of residence for a
project these last 6 months.

Testing is a bit difficult for me. My WAF goes down when I spent part of
the week end on the TV computer testing stuff instead of spending
quality time with the family.  Also, I do not want to leave the only TV
system in the house in an unstable state right before leaving for a

However, it seems that my problems with the 1.20 firmware were most
probably due to leftover 1.10 files scattered
around /lib/firmware/linux*.

I may be wrong and I did not spend much time on this, as I reverted to
1.10 before boarding yet another plane.

I may have experienced a remote control issue too.

But again, I did not take the time to properly sit in front of the
system and test things with a clear mind and some proper process.


Maybe this week-end.
