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.
Similar NFS issues here every now and then: NFS: v4 server 192.168.1.90 does not accept raw uid/gids. Reenabling the idmapper.
