I've had the same problem.

 From what I've been able to gather from the LKML is that this occurred 
before the 3.2 staging merge.

I'm looking forward to trying it out UA25EX / Asus N53SV (7 series) - 
would have done so already but my equipment is still in transit. Will 
let you know in a week or so when my container gets here.

regards,

Brendan
