Bug Description
Steps to reproduce the bug:
1. Install Ubuntu 14.04.1 on the Cisco M-series server.
2. Run reboot test, OS will come up and go for graceful reboot continuously.
3. I am seeing kernel panic in 3 out of 4 Ubuntu machines . Don't know after how many iterations of reboot it happened. I checked the server 6 hours after starting the reboot test.
4. Don't know whether this panic is happening while the OS was booting or while going for reboot.
The bug has been root caused to the enic driver and a fix has been posted upstream.
Please find below the details of the patch submitted upstream.
