something just crossed my mind here: you said you were doing direct I/O, right?

Doesn't that mean user space right to block device? Simply based on
that, I can  see you fail all these times... because you do it from
kernel space..and that's against the very  basic meaning of direct I/O

Warning: this is a thought from non filesystem guy :D
