Is this reproducible without the power cut? And what model SSD are
you using, and are you sure that it has Power Loss Protection (many
SSD vendors use power loss protection as the price discrimination
feature between consumer-grade SSD and enterprise-grade SSD's that
cost $$$). If this problem wasn't showing up with 4.2, and is only
failing with 4.3-rcX, then it might not be a hardware issue --- but
it's also possible that there was a timing issue which was hiding a
hardware problem. So for the purposes of debugging, removing the
power cut from the set of variables is a useful thing to do.
