Hi Aditya, That's good news!
Thanks for letting us know.

The events thread is no longer stealing the cpu with any of the e1000e-1.x drivers. Thanks for the suggestion. I have attached the output of ethtool anyway. There were no specific patterns with the issue, it would start as soon I loaded the module and brought up eth0. I still haven't tried with the link connected, and if that happens to cause problems when do I get a chance to test it, I will let you know.
