HI Danny, Not saying that it couldn't be a driver issue, but I've been loading my rootfs over out network for a long time( read: close to two years, with various kernels ), and have never even seem one dropped packet, let alone 5-10%. I've also done some minimal testing of network mounted file systems, e.g. using dd to write / read from a remote mount. Using both iSCSI, and NFS, while observing no dropped packets. The interface was also maxed out from what I could tell ( 11MB/s + ).
So while I obviously can not give you a concrete answer, I would definitely look into cabling / internet stability. Especially if the internet used is wireless . . .
