Yes Jens it is ppc64
I'm pretty sure we have some memory ordering issues, or perhaps the barriers on ppc64 are just wrong. I'll have to check them.
The job:
cmd="$FIO --name=test --group_reporting=1 --ioengine=libaio --invalidate=1 --iodepth=32 --bs=4K --filename=/dev/sde --rw=randread --direct=1 --buffered=0 --time_based --runtime=300 --numjobs=64"
does indeed have 32 * 64 potentially pending, which is huge. So there are valid questions on whether this is really what you want. But regardless of that, it should not pose a problem for fio.
Is this on Linux? If so, can you send the output of /proc/cpuinfo, so I can see what CPU this is exactly.
