Thanks for posting this!

I was wondering why nfs was suddenly very slow, and lots of data was
flying round the network...

Reverting from kernel 53.1.6 to 53.1.4 on server and clients has fixed
it for me. It only seems to affect x86_64 systems, or affects them
much more noticeably than it does i386 ones.
