I have noticed this issue with a unpached kernel too. The "mm fix page writeback accounting to fix oom condition under heavy I/O" patch makes the problem reproduceable. Sometimes the io wait time is at 100%. Sometimes there is no io wait time. There is no problem with read access, but no write access is executed. I can reproduce the problem with xfs. With ext4 the problem does not appear very often on the patched and unpatched kernel.
