Re: Fwd: Ehernet FEC problem in Coldfire M5272C3

Hi Greg,
I had a look at all the patches made for M5272C3 in cvs.org for kernel
2.4.x in last couple of years. It seems all patches are included in my
distribution (uClinux-dist-20120401.tar.bz2). I don't have idea why this
error NETDEV WATCHDOG is still coming. I am running at 50Mhz clock
frequency. Is there any problem with frequency?


Thanks
Ashish Phogat
