Libertas firmware on F9 for the XS

[Michail Bletsas]

Martin,

I really miss the point of your tirade.
Our advice is to use 5.110.22.p18

Offtopic datapoint: here in my NZ office all signals are WPA encoded,
from various APs I don't control (but can use). "Certain" is
unfortunately around 80-90% of the cases.

Is trac being used reasonably to track firmware issues? Checked
earlier today - 'component = wireless' and 'summary contains libertas'
kinda sorta give an overview. False matches and untriaged issues
abound so it doesn't seem like anyone's looking at that "view" of the
data.

(Me, I only sleep when by this trac "view" tells me to:
https://dev.laptop.org/query?group=status&milestone=xs-0.5 )

Perhaps Michails has a spreadsheet or wikipage hiding somewhere? ;-)
You guys have been doing a ton of development (both features,
bugfixes) dealing with several moving parts -- notes of "what works
where" and "what clearly barfs" must be collected somewhere.

cheers,
