xircom_tulip + NFS hanging interface

[Pau]

I've been getting problems all along the pre-2.4 series and 2.4 itself
when I use NFS to play mp3 files with xmms.

The message in the logs is:
tulip.c: outl_CSR6 too many attempts,csr5=0x60208100

After a few times the network stops working and it only recovers with the
following sequence of commands:

ifdown eth0 && ifup eth0 && ifconfig eth0 -promisc

Without ifconfig eth0 -promisc it still doesn't get any packet.
I have to stop and start the interface too ad -prmisc doesn't work alone.
So this is the only sequence that works.

The modules loaded are:
