With all due respect, go away. This is all you do on these forums and it’s childish, shortsighted, and annoying.
Seems that examples of different users with systems that boot up just fine, yet keep hitting I/O errors on reads and writes and keep giving false positives on ZFS checksum errors, is a “repeatable” issue.
Give it a rest already. It takes very little time to run memtests and rule out something. It’s not a big deal. I don’t know why you keep making it into such a hysterical problem that you need to always jump in and lecture other users.
