I don't have any ideas about debugging this, but I do have an idea about where you might get more help. Post a message to LKML, and don't describe it as a suspend problem. Instead, describe it as a problem enabling CPU cores after the system has gone through a suspend/resume cycle. This may help attract the attention of people who are familiar with the issues involved in enabling and disabling CPUs -- which appears to be the source of your difficulties.
