I don't think so, I just rebuilt the OS less than a week ago and used the same driver reference in the wiki.
I had it crash twice doing a benchmark, so I think power might be it, just interesting I never this this problem with this setup for a couple weeks in Windows (before this I had 280x cards which were a little less power hungry, but had awful cooling).
I think it's probably because there are still 100+ hashes pending on that run that's slowing it down for hashrate, benchmark seems to be where it should be.
