First of all , thanks to all who replied,
It is definetely related to interrupts since starting the target without =
the eth wire plugged enables me to login into the board. Of course, =
without network connectivity......and whenever the wire is connected ->the =
board freezes again (no message, no panic, nothing....).
The boot process seems everything ok, the request_irq returns ok for both =
the mii and the fcc. I am not using a commercial board and some tuning =
were made to the kernel to adjust to the hardware configuration, mainly =
clocks and MDIO pins. I took changes somebody made with DENX's 2.4.18 and =
ported them to 2.4.25, probably forgeting something in the way....may be =
something related to interrupts interfaces has changed since then???=20
Any feedback will be higly wellcome,
Samuel.

Check that the interrupt from the LXT971 is configured correctly.
The code is probably waiting for this interrupt to tell it that negotiation=
is complete
