[Commotion-dev] Boilerplate Android code pushed

Thu Feb 2 21:58:41 UTC 2012

Ah, we've had some strange reports like that from CM7 users.
No we don't write over any files in the system folder. At least not directly.
We'll probably end up trying to use our "generic" chipset profile
which will try to call /system/lib/libhardware_legacy.so
wifi_load_driver() / wifi_unload_driver().
CM7 seems to include this library, but using it might be the cause of
this issue. We haven't flashed CM7 onto any of our phones yet to test
what the root cause is.
You may need to boot into recovery mode and clear the cache, or worst
case do a factory reset.
