Hello all, i have the same problem with the fec driver. See my posting at http://ozlabs.org/pipermail/linuxppc-embedded/2008-January/029466.html Arnon, have you already fixed the FEC problem?

I'm using Domen's new FEC code and ATA from 2.6.24-rc2. I tried our kernel (see link above) with an external harddisk and NFS. I copied various files from the harddisk to NFS root and vice versa. No data corruption. Can you check our patch stack on your hardware? Juergen -- Dipl.-Ing.

Yes, we do, on the phyCORE-MPC5200B-tiny; you can check our patches here: http://www.pengutronix.de/oselas/bsp/phytec/download/phyCORE-MPC5200B-tiny/ We've recently made the -6 release which supports ATA; although I'm not sure if the tests were done with networking & ATA at the same time I assume yes (at least while doing nfsroot).
