This looks more like a watchdog problem on your card's driver. I have
seen a similar problem in 2 cards, and patching their drivers to skip
watchdog's initialization fixed that. I guess your driver is called
dmfe, right? The only useful parameter I can see for this driver is
'debug=1', which may be of some help for you.

By giving a quick look at its sources, maybe recompiling it with the
following patch does the trick:

--- build/drivers/net/tulip/dmfe.c.orig 2006-12-16 03:31:20.000000000 -0200
+++ build/drivers/net/tulip/dmfe.c      2006-12-16 03:31:29.000000000 -0200

        /* Enable DM910X Tx/Rx function */
        db->cr6_data |= CR6_RXSC | CR6_TXSC | 0x40000;

Do you have a way to recompile and test it there? Do you have 013
installed in one of your partitions, or are you testing it from the
live cd?
