Supermicro IPMI disconnects when os boots.

There is an issue with the e1000e driver when using the supermicro IPMI BMC2 card. When the OS boots you loose all connection to the BMC2 card.
To fix this you have to disable CRC Checking in the e1000e driver.


To do this on Ubuntu add/edit the following file. Add the following kernel boot parameters to /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="e1000e.CrcStripping=0"
update-grub
reboot

Reboot your server and your IPMI will stay active. Your checking for the following
