Yes, I am running kernel- .
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.
