output of /usr/bin/df -hT would be a good idea

if you heave /tmp as tmpfs like more and more linux distributions
set "tmpdir" in my.cnf somewhere else, O_DIRECT can not work on
tmpfs by definition and that there was before no warning don't
mean that it ever worked before

there where many warnings in the past 6 months about config options
which are deprecated or not work as someone may think

the difference is "works not" silent or not silent in most cases
