Bug Description
[Impact]
On the majority of boots, the mlx4 driver will fail to initialize, resulting in no network connectivity. This only occurs if debug level
logging to the serial console is enabled - which is not the default in Ubuntu.
[Test Case]
Enable debug logging:
$ echo 'setenv bootargs "$bootargs debug"' > /etc/flash-
$ sudo flash-kernel
And reboot.
[Regression Risk]
The MSI code being modified in question is only used on X-Gene systems, so risk to other systems is insignificant. In addition, the code being removed are just debug statements that aren't emitted by default today in Ubuntu, so even for X-Gene systems it is a minimal risk.
