Hi Korey, I ran into a similar problem with a different benchmark/boot up attempt. There is another thread on m5-dev with 'Ruby FS failing with recent changesets' as the subject. I was able to track down the changeset which it was coming from, but I did not look further into the changeset as to why it was causing it.
Brad said he would take a look at it, but I am not sure if he was able to reproduce the problem.
