I just tried fio 3.28, and it worked for me. So I don't think it's
fio.
Luis, could it be related to a kernel config option?
Here's the kernel config that I'm using. Can you try copying the
attached file to your .config, and then run "make olddefconfig", and
then rebuild your kernel, and see if that works for you? If so, then
we'll try to narrow down which kernel config is making the difference.
The other potential difference is that my test appliance is currently
built using Debian 10 ("Buster"). There can be glibc or other
userspace dependencies which make be making a difference, but that
seems unlikely given that generic/095 is a pretty old test, and it's
not trying to use anything new/exotic like io_uring.
