Question I am using the SIMLC IPMI card in X7DCL-3 motherboard. The IPMI card stopped responding over the network as soon as the Intel e1000e LAN driver was loaded in CentOS 5.3, and started working as soon as it was unloaded. I did update to the latest driver from the Intel website, and confirmed that the new modules were loaded. How can I make the IPMI work? Answer The hardware CRC checking option in the kernel prevents the LAN1 port from working correctly with IPMI. The solution is to create a file /etc/modprobe.d/e1000e.conf with the following line: options e1000e CrcStripping=0 and to reload the e1000e module or reboot. Was this FAQ helpful?
