Problem with hibernation

[Timothy Murphy]

My laptop has ceased hibernating.
When I click on f=>Leave=>Hibernate
the sleep-moon starts flashing
and the small hyphen-like symbol on the top left comes on as usual,
but as far as I can see nothing is written to disk.

At this point it becomes impossible to communicate with the machine.
Ctrl-Alt-F2 does bring on a text window,
with a login: request,
but if I enter my username and press Return
I am not asked for a password.
Whatever I type appears on the screen,
but with no effect.

I tried stopping the NetworkManager and openvpn services
which seemed to me the most likely causes of the problem,
but that had no effect.

I wonder if anyone has had the same problem?
And if so, whether there is a solution?

I'm running the current kernel,
but I tried the last 2 kernels without effect.
