not yet! @Alex: any idea on your side (change of the default driver or
something alike)
this seems to be a timing or reading problem according to the "short
read" msg

Artin, can you also post the debug drivers's output of 2.2.1 for comparing?

First of all I want to note that there is no phoenix subdriver in both 
the official 2.2.1 and 2.2.2 sources. If my memory serves me well I once
sent a patch to Chuck that added it and some other stuff from the trunk.
So the driver in 2.2.1 package was mostly the same as in the trunk
because of this patch. It seems to me that something happened with this
patch in 2.2.2 package (because 2.2.2 still lacks the new phoenix
subdriver). So you see, it was actually a downgrade.

The thing that confused me at first is that the 2.2.2 version log tells
that the agiler subdriver is used. But this is just an error in log
text. In fact it uses agiler_old subdriver which doesn't work with some
models (like Artin's). Since this is already an official release, I
can't fix it. @Arnaud: when will be the next? :) I think phoenix
subdriver should be there.
