Maybe turning off sendfile or NAPI just lead to random success - so far it
really looks like tso on the r8169 is the common cause.

TSO on the r8169 is the magic switch but the regression makes imvho more
sense from a VM pov:

- the corrupted file has the same size as the expected file
- the corrupted file exhibits holes which come as a multiple of 4096 bytes
(8*4k, 2 places, there may be more)
...

That's interesting. I had the those exact same symptoms here
with copying data to/from a USB stick recently.
But that stick died completely shortly thereafter,
so this was written-off as "bad hardware".

Strange that you see the same symptoms from a different scenario.
Probably no relationship there, but ..
