Default linux 3.4-1

Hi,

Starting with linux 3.4-1 I'm getting random corruptions when reading
files from my file server over nfs and we've also seen problems with
packages downloaded from our mirror on brynhild.

The files on disk validate just fine (md5sum), it's just the transfer
that seems to break.

linux-lts 3.032-1 and linux 3.3.7-1 are good.
