Did you ever observe that behavior on a lite5200 ?
What is 'long uptime' and do you have sustained transfer during that
period ? (To try reproduice the problem).

Weeks uptime. We don't work with the lite5200 for so long time, but our
board is based on a lite5200, and the FEC configuration is exactly
equal.

Also, what are the 'symptoms' ? (anything in dmesg ?)

FEC doesn't work at all, everything else works. If using a console I
execute 'ifconfig eth0 down && ifconfig eth0 up <IP>' the fec starts
working again.
I haven't reproduced it directly, but a partner and a customer. I'll try
to reproduce this behaviour myself and bring back more information.

I haven't touched the FEC code much except to remove the
aligment code (newer bestcomm microcode doesn't require alignement of
the skb). 

You can send me the driver/net/fec_mpc52xx and arch/ppc/syslib/bestcomm
you're using, I'll tell you if there was major changes.

I've sent to you the patches that I extracted from your kernel source
tree some time ago.
I have all the patches until the 1.2161 one. But I've only sent to you
the ones related to the FEC and the bestcomm.
