+Commit 913a89f009d9 ("ipmi: Don't initialize anything in the core until
+something uses it") added new locking which broke context.

+
+ RHEL-only
+
+ The ARM-based HPE m400 reports host-side ipmi as residing in intel
+ port-io space, which does not exist in ARM processors. Therefore, when
+ running on an m400, host-side ipmi configuration code must simply return
+ zero without trying to configure the host-side ipmi.
+
+ This patch prevents panic on boot by averting attempts to configure
+ host-side ipmi on this platform.
+
+ Though HPE m400 is not certified with RHEL, and HPE has relegated it to
+ EOL status, the platform is still used extensively in ARM development
+ and test for RHEL.
+
+ Testing:
+ Boot without blacklisting ipmi and check to see that no ipmi modules
+ are loaded.
