Package: acpi
Version: 1.6-1
Severity: normal

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?
   * What outcome did you expect instead?

I am not sure for 100% that it is acpi.

I've purchased LENOVO ThinkPad L512 (2597AB2) laptop, and experiencing some problems with 
it in Linux. Particularly, after some time (it may be 10 minutes, or may be day) 
buttons Fn + F1, Fn + F2, ..., Fn + F12, Insert, Delete, Home, Volume+, Volume-, 
Volume Mute are no longer works (all button Fn+"*"). Also CPU fan behaves strangely: 
it stops, then it goes to it's max RPM, than it stops again, etc. And it does so until one 
completely cuts laptop from the power (no AC, no battery), reboot or on/off cycle are unhelpful.

tried other distribution kit in particular ubuntu 12.04.1, in it acpid-2.0.10 and 
everything perfectly worked also with cpu fan and Fn buttons.
