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 . . .
