Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Running /usr/sbin/powertop --auto-tune

left the optical mouse LED off and the cursor frozen in X.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

restarting pc and not running:

 /usr/sbin/powertop --auto-tune

left the mouse running fine.

dmesg reports mouse as:

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Cross-grading from i386 to amd64 must have re-enabled auto-tune and disabled my mouse, found my own bug report from more than 3 years ago.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Removed/purged the powertop progam fixed things.

   * What was the outcome of this action?
   * What outcome did you expect instead?

It would be good to have some confirmation to dmesg/syslog when powertop does something like this.
