+# ME Cleaner
+It's possible to 'clean' the ME partition within the flash medium as part
+of the build process. While cleaning as much code as possible is removed
+from the ME firmware partition. In this state the ME errors out and doesn't
+operate any more.
+
+**Using a 'cleaned' ME partition may lead to issues and its use should be
+carefully evaulated.**
+
+## Observations with 'cleaned' ME
+
+* Instable LPC bus
+ * SuperIO is malfunctioning
+ * TPM is malfunctioning
+ * Random system shutdowns on high bus activity
+
+## Filing bug reports
+
+Always test with unmodified IFD and ME section before reporting bugs to the
+coreboot project.
