I have what appears to be the same problem with my Dell Mini 1012 in the current 10.10 beta. This seems to be a regression, since suspend/resume worked fine for me in 10.04.

I tried the workaround found at http://ubuntuforums.org/showpost.php?p=6105510&postcount=12 and it appears to work. This bug was fixed back in intrepid, but seems to have showed up again. Unfortunately, I have no idea which prior bug this is related to.

The basic idea if the workaround is that if you disable all but one CPU before suspend, the machine will resume properly. Once your machine has resumed, it re-enables the other CPU(s).
