Indeed. It helps to the point that without that option it doesn't even 
mount root :-)

Maybe you have a theory on what's going on. When I copy a file, what I 
get on the NFS server is a file of the same size, but with chunks of 
zeros interleaved, that is:

0x0000 <correct data>
0x1000 <zeros>
0x2000 <correct data>
0x3000 <zeros>

It's annoying how regular it is :-)
