After experiencing the joy and the meaning of "stability" and what it feels like, I decided to upgrade to kernel 3.7.9 (the latest stable) from 3.7.4 and voila... this bug reared its ugly head again after the first hibernate/restore cycle. This is what I get: kernel: PM: Syncing filesystems ... done. kernel: Freezing user space processes ...
