Hi,
I am facing a very old problem with my Ethernet connection on M5272C3
coldfire board. As soon as my uclinux boots I got the following logs shown
below:


Command: cat /etc/motd

Spurious interrupt 1


uclinux simply hangs there. I found that there is a large amount of people
who are getting the same problem in past couple of years. But I did not get
any solution for the problem.

Please let me know whether this problem still exists in uclinux source code
for M5272C3. where I will find the solution for that?

My Ethernet Hardware Info:
fec.c: Probe number 1 with 0x0000
eth0: FEC ENET Version 0.2, 00:e0:0c:bc:e5:60
fec: PHY @ 0x1, ID 0x0022561b -- AM79C874

Thanks and Appreciated for your help.

Thanks
