I've added a considerable amount of debug into the suspend path in the kernel.
1. Edit /etc/default/grub and set: GRUB_CMDLINE_LINUX_DEFAULT="loglevel=7 no_console_suspend" 2. Download and install the kernel .debs from: http://kernel.ubuntu.com/~cking/lp-1228406/v1/ 3. Reboot 4. Switch to console #1 5. login 6. run: sudo pm-suspend Note down the last kernel messages you see. If the screen blanks and the machine turns off before you see any messages, I will add some delays to printk() when suspend in invoked and re-spin a new kernel.
