Hi All,
I have following kernel Oops when I run ifconfig to setup the UEC0 of
MPC8360MDS board. There is no hardware problem, the UEC0 runs well
under Uboot.
Any idea on this issue?
Thanks,
Mike

does this occur on vanilla u-boot and kernel versions? if so, which
ones, and on what board revision?

might want to turn on verbose debugging while you're at it.

The kernel Oops happened under Linux when I try to use "ifconfig" to
setup the eth0. Under Uboot, the UEC0 works fine. I am able to do
ping, tftp via the ethernet port.

Oh, I forgot to metion just now. The linux is based on a custom built
kernel 2.4.22, not from Freescale.

Enable the debug flag on ucc_geth.c: there is the dmesg:
ucc_geth_open: IN
ucc_geth_startup: IN
Machine check in kernel mode.
