Perhaps there were two or more problems here. > Basically, the way thing stand now is that merging the pmap fix from i386 fixes the fault-on-nofault-entry panics, but there remains a memory corruption problem.

Silby claims to have seen this (install failure) on x86, so at least its not alpha specific. Drew
