Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm this problem on a Thinkpad T520.

Same here on a T420s.

Sorry, I meant T420 (sans the s).

Does anyone still experience this in precise or later?

[Rolf Leggewie (r0lf)]

I believe this is fixed in the latest 0.41 release as documented in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=628829

Can you please verify?
