I have the same model and haven't seen any such problem, though it's
possible I haven't done a shutdown (vs suspend or reboot) for quite a
while.

Try removing nvidia.

Default Bug#684240: linux-image-3.2.0-3-686-pae: lenovo t61 laptop fails to shutdown

At one time I had problems with my graphics card and they were solved
installing the proprietary nvidia driver. Could that be the problem?
The message 'driver taints kernel' makes me somewhat nervous, but it
has worked fine for a long time.
Regards,
Luis

The 'taint' mechanism is used to flag anything that might cause
instability and that can't easily be supported by kernel developers.
For example, some hardware problems, and proprietary modules. I realise
that many people use the nvidia driver without problems, but in case it
does cause a problem neither Debian nor upstream kernel maintainers
should be expected to support it.

So the obvious first thing to test is whether the problem goes away when
it is not loaded. (Note: loading then removing it does not necessarily
have the same effect. You have to make sure it doesn't get loaded at
all, either by using modprobe's 'blacklist' directive or by removing the
module from the disk.)

Ben.

Dear Ben,
I tried, but after blacklisting nvidia, commenting out
nvidia-kernel-common.conf and running update-initramfs -u to avoid
nvidia being loaded, the noveau driver was loaded instead and the
video of my laptop became useless. I couldn't use nor X nor the text
consoles. I had to boot from a live CD to revert my changes and load
nvidia again.
Regards,
Luis
