Hi zigo, According to the upstream temporary fix[1], the ZFS SIMD issue is specific to x86 architecture. It affects the following 3 parts of ZFS:
1. fast fletcher checksum (sse*, avx*) (used for data integrity check) 2. raidz 3. illumos crypto library Some architectures such as ppc64el are not affected at all. Plus, ZFS encryption is a feature introduced since 0.8.0, and 0.7.X doesn't have it.
