    The only thing visible here is a power management issue, since that driver is the one that is crashing. Could be a lot of things. Is there a particular thing you are doing? Is it sleep related?

    Hmm.. is there any relation to the strange slow Radeon 7XXX issues with the Mac Pro 3,1 on Mavericks:

    I have had crashes like these frequently for years. finally fixed it with macrumors. It was Bad RAM. Had nothing to do with power management.

    Use Memtest86 and do a test.
