system freezing mid upgrade (to 12.04)

I'm in the process of upgrading to 12.04 (via command line, from 11.10).

Everything was downloaded and it was happily unpacking and replacing packages when my system froze.

I can move my mouse, but clicking on anything gets no response, and the display is not changing other than the mouse moving.

What can I do? I'm guessing simply holding down the power button until it turns off is a bad idea, but I don't know what else to do that would get things moving again.

(I couldn't find this question, but if it has already been asked and answered then a link would be helpful.)

Thanks!

This looks like a software failure, and you can try to power it down with the power button(hard reboot). If you are concerned about general FS, corruption, you can try the REISUB trick. Just hold down [ALT]+[SYSRQ]+[[KEY]], replacing [[KEY]] with R, then E, then I, then S, then U, then B, waiting a few seconds between each. If at the end it does not hard reset, use the power button. If you have issues after the reboot, try using dpkg -a or apt-get to remove any offending packages.
