I'm not sure exactly of what we're talking about here. Could you or
Deepak clarify what are these issues?

In fact, we are fixing timing issues that prevent the XO to connect to
certain WPA access points under certain conditions (timing in 802.11
is influenced by external conditions too, hence the randomness and
intermittent behavior and the need of using "certain")

There are other possible hot areas that should not be a problem for
the XS (as suspend/resume interactions with wireless and problems in
some XO's wlan modules (do not enumerate -  still not clear to me if
this is related to the firmware)

If there are other bugs (and there is always corner cases) they are
bellow my radar now.
