Not sure what the situation is on Solaris, but at least on Linux the
file system has to support direct IO. What file system do you have on
/tmp? Does it work if you place the files somewhere else?

I used to have a small T2 box on my desk that could boot into Solaris,
that's where I did the initial port and testing. But I don't anymore.
But to be honest, I would rather rely on someone trusted to tell me that
it works on platform XYZ, I just don't have the resources to run a full
battery of tests on all the platforms that fio supports every time I do
a release.
