Binary package hint: pm-utils
When doing the ubuntu system testing and also in my daily use of this laptop I cannot get it to suspend. It goes like it is about to suspend but then it gets to a blank backlit screen and stays there, requiring a forced shutdown. I'm running 10.10 RC 64bit and have have also run 10.04 64 but wit no avail. Any and all help looking into this would be appreciated.

got into same problem and successfully solved it using a how-to found somewhere (i can't find it again, sadly).
The problem is with usb3 drivers, all you need to do is unbind those and rebind after resume.
0000:00:1a.0 and 0000:00:1d.0 are files found with something like ls /sys/bus/
There is still some minor flaw, the keyboard keeps blinking while the computer is suspended, but not a big deal.
cat /etc/pm/
#!/bin/sh
case "${1}" in
# Unbind ehci_hcd for first device XXXX:XX:XX.X:
echo -n "0000:00:1a.0" | tee /sys/bus/
# Unbind ehci_hcd for second device XXXX:XX:XX.X:
echo -n "0000:00:1d.0" | tee /sys/bus/
;;
# Bind ehci_hcd for first device XXXX:XX:XX.X:
echo -n "0000:00:1a.0" | tee /sys/bus/
# Bind ehci_hcd for second device XXXX:XX:XX.X:
echo -n "0000:00:1d.0" | tee /sys/bus/
