Unfortunately I don't have access to a qemu instance to test this any
more :)

Title:
Combining direct_io and non-direct_io leads to hang
Status in QEMU:
Incomplete
Bug description:
Version 0.12.2 - I know this isn't the latest but I looked through the
changelogs and couldn't find any references to this being fixed.
This is related to issues that many apps have, and is described in more
detail here:
http://oss.sgi.com/archives/xfs/2010-07/msg00163.html
and:

When using both direct io and buffered io on the same file, you can cause
corruption on the filesystem and other issues.
XFS out right hangs, but the problem exists on ext3 and other filesystems
which silently carry on.
**this is a data corruption issue**.
This is the full stack trace we got from a recent hang:
