Hi list,

is there anyone out there successfully using the SMC 91C111 ethernet chip on AMD's DBAU1200 eval kit? In my setup here, it's working fine from within the YAMON boot loader so I can use it to download a kernel image via TFTP.
The kernel (bleeding edge linux-2.6 mips-GIT) detects the device as well

        smc91x.c: v1.1, sep 22 2004 by Nicolas Pitre <nico@cam.org>
        eth0: SMC91C11xFD (rev 1) at b9000300 IRQ 65 [nowait]
        eth0: Ethernet addr: 00:00:1a:19:11:8c

and is able to mount its root filesystem via NFS. However, the communication does not seem to be sufficiently stable, messages like this occur regularily:

        nfs: server 192.168.1.200 not responding, still trying
        nfs: server 192.168.1.200 not responding, still trying

As the machine acts as NFS server for several other linux embedded systems, I don't suspect it to be the problem. Also, things like cables etc have been
properly checked.

Before I'm starting research, I'd like to know whether this is a known
issue or whether there are any mandatory settings I missed.

Thanks for any hint,
Daniel
