+  * test/autopkgtest_kernel_patterns.py: Anchor running_escaped_regexp to
+    ensure the test operates correctly on architectures which have kernel
+    flavors that are prefixes of other flavors (e.g. -generic and -generic-64k
+    under arm64).
+  * d/t/control: Restrict kernel-patterns test to isolation-machine as the
+    test assumes a meaningful link between the running kernel and the archive
