+Subject: [PATCH] Add a workaround for spurious CPU errors
+
+There is a possible issue where GPIO event interrupts are getting
+missed causing false errors to be logged.
+
+This adds a check that the host is still on and the error is still
+asserted before logging an error.
+
+Tested:
+Confirmed that a spurious SMI event was ignored correctly after
+this change.
