+config SANDBOX_CRASH_RESET
+	bool "Reset on crash"
+	help
+	  If an illegal instruction or an illegal memory access occurs, the
+	  sandbox by default writes a crash dump and exits. If you set this
+	  flag, the sandbox is reset instead. This may be useful when running
+	  test suites like the UEFI self certification test which continue
+	  with the next test after a crash.
