Hi Shawn,
I had the same problem with the same situation but I have a static ip and pretty much a normal install of 4.6.3 with pg 7.3.2 (or is it 7.3.3...). I haven't gotten around to posting about it or digging into the error but I can at least say that there's no mention of it in bugtracker or in the forums as far as I can tell - just the problem where mounting at a folder called etp craps out. Not much help but at least verifies your problem.
