Hello,
I ran into the following warning when running v4.4-rc3 on a TI OMAP4
(pandaboard) using nfsroot.

The problem occurred twice only over several hours and wasn't linked to any
particular operation.
Before the first occurrence I also got errors printed right after boot on both
the client and the server side kernel logs. The server side read as follows.
[72948.929645] oversized read request from 192.168.1.254, port=938 (1426618135
bytes)
[72954.726793] oversized read request from 192.168.1.254, port=938 (67248960
bytes)
I'm afraid the client messages have been lost in my scroll buffer, but they
were related to the to oversized requests as well.
I've been running the same setup on v4.3 without any issue for quite a long
time.
