Are there more of these stalls?
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.
