I believe that "msk0: Uncorretable PCI Express error" wasn't relevant to the freeze because it also happened before I replaced vge(4). I guess the system froze while initializing vge(4), but I'm not really sure actually. What can I do to narrow the cause of problems? Is it useful to build kernel with options KDB and DDB?
