On some systems using the Cisco enic driver, a kernel configured for kdump may hang while attempting to load the megaraid_sas module. This issue has been identified on a Cisco UCS B230 server. The problem appears to be resolved by disabling the Cisco enic driver.

Workaround: To disable the Cisco enic driver, add the following line to the /etc/kdump.conf file:

 blacklist enic
