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.

If by current kernel you mean kernel-2.6.33.8-149.fc13.i686 then I already tested the hibernation and it works - i.e. it does hibernate the machine.

Yes, I am running kernel-2.6.33.8-149.fc13.i686 . But I probably did not express myself properly; I also tried the previous 2 kernels, and had the same hibernation problem with both, from which I deduce that the problem has nothing to do with the kernel.
Actually I only have this problem on one Thinkpad T43 laptop; hibernation works perfectly on a second T43.
I suppose my main difficulty is that I don't know how I can find out what is going on in the laptop at the moment of failure, since the only way I can see to bring the machine back to life is to press the power-button, and then re-boot. There doesn't seem to be anything odd in /var/log/messages after this to explain the problem.

I saw this (on somewhat similar hw - a T60) when I have an secondary hdd in ultrabay (not all the times though) or when I have an nfs mount (always).
HTH,

I solved my problem by adding RAM - there was 512MB, and I added 1GB. After this, to my surprise, hibernation worked again. So it seems the cause was a shortage of memory. I'm rather surprised, as I have (and had) 2GB swap space.

I would consider submitting a bug report against kernel.

That is certainly surprising since hibernation saves the state of the system to a disk file. Now if it was suspend it would make sense that adding RAM would be helpful.
