I've read other threads like this, as I sometimes had the same problem on an Lenovo X301. The workaround for me was to switch to just one cpu core before suspending/hibernating. When you resume/thaw, give it a few seconds and switch the other core back on. This worked for me. The theory is that there is a multi-threading issue somewhere which can affect multi-core CPU, perhaps just these low-power ones. You can automate the fix with a script in /etc/pm/sleep.d/, see thread for example:
