One further comment: > This patch appears to fix my machine check problem on the 4kc. The 4kc > shouldn't need an ssnop here, but this appears to fix it. The 4Kc shouldn't need an ssnop/ehb for the purposes of a *load*, but if the exception was on an instruction fetch, the documentation is reasonably clear that there's a hazard of 3 cycles before the new entry can be used for a fetch - which is what ERET will do in the case of a instruction fetch miss.
