Comment 4 for bug 1509929

Checking the referred links it sounds indeed like the following patch is required for the e1000e driver (even or because it is not in use). Seems like it has been asked to be included in 4.2 before release but nothing happened. Did not see it either in Dave Millers most recent stable mbox. I am preparing a test kernel and will update this report with a link once done.

Subject: [PATCH] e1000e: Fix tight loop implementation of systime read
 algorithm

Change the algorithm. Read systimel twice and check for overflow.
If there was no overflow, use the first value.
If there was an overflow, read systimeh again and use the second
systimel value.
