Yes, I only touched vge(4). 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?
