Hm, the length looks like a negative number (-884). I don't see why the 
firmware should report negative length, however. May also be a simple 
integer underflow for whatever reason.
In any case, I think the firmware probably died and responds with crap. 
Which would also explain the suspend failures.

Are there any LP specific hostflags that need to be set in AP mode?
