Then it tries to\nrewrite the PTEs via a stale CPU mapping. This causes panic.\n\n[vsyrjala: Add TODO comment]\n(cherry picked from commit 51064d471c53dcc8eddd2333c3f1c1d9131ba36c)"

En algunos escenarios, el objeto DPT se reduce pero el framebuffer real no y, por lo tanto, sigue ah\u00ed en vm->bound_list del DPT. Luego intenta reescribir las PTE mediante una asignaci\u00f3n de CPU obsoleta. Esto provoca p\u00e1nico.
