Comment 5 for bug 760842

I'm also affected by this, although on a desktop machine: i5 2500K, Asus P8P67-M Pro, Nvidia GT210.
Suspend fails on Ubuntu 10.04, 10.10 and 11.04.

As described, only a hard reset helps to restart the computer, the reset button does nothing.
There is no video signal, but the harddisk seems to spin up 2-3 times after abruptly stopping.
