Bug#762148: Fix intel_pstate kernel panic in wheezy, already done upstream



Package: linux-image-3.2.0-4-amd64
Version: 3.2.60-1+deb7u3
Severity: normal
Tags: patch

Hi kernel folks,

The intel_pstate driver in wheezy fails to calculate its timer timeout correctly, which can cause the driver to race with itself. Google's kernel engineers identified this as the cause for an occasional kernel panic which our test infrastructure picked up. The fix is one-line and was accepted upstream in April of last year.

Could you please apply the one-line fix to the next wheezy stable update? While we've only encountered this infrequently, this is the kind of patch that can only help things.

Thanks!
