I recommend reading sifive's errata, at least the ones it's possible to get ahold of. They are consistently wild, for multiple CPU IP generations. Some paraphrases that come to mind: "mmu doesn't work; workaround: don't use it" and "exception cause register not sign-extended; workaround: don't cause page faults on addresses in that half of memory". |
