I haven't seen the same kinds of logging in dmesg, but a few minutes ago I did see that the desktop had locked up and after remotely logging in and doing a kill -HUP of iceweasel/firefox, saw this: [92311.944443] swap_info_get: Bad swap offset entry 000ffffd [92311.944449] swap_info_get: Bad swap offset entry 000ffffe [92311.944451] swap_info_get: Bad swap offset entry 000fffff I've since restarted that machine, but should it happen again I'd be happy to run further tests.
