Kernel panic: eth0: PHY id 0x31903190 is not supported!

[Steven Blakeslee]

I've booted the linuxppc_2_4_devel tree on the EP405PC and the ethernet
worked fine.

Hi,

I loaded a 2.4.18 linux kernel onto my ICE Planet box ( a PPC box with EP
405PC board and a 405GP chip) but when the kernel uncompresses itself and
tries to start up I got the an error message:

I did some debuggings and found that the error message " eth0: PHY id
0x31903190 is not supported!" is generated by the file "ibm.ocp_phy.c"
within the kernel source code.

Has anyone encountered this problem before?  I am just curious if my
ethernet card is bad or it is not supported by this kernel.

Any help is appreciated.

Andy

p.s. ibm.ocp.phy.c is attached below.
