Hi,

I have a custom board with MPC8275 and NFS root file system. I use u-boot to load the kernel and it boots up, mounts the file system and starts /sbin/init. Then all the children of init dies, I get the following errors (with Debugging enabled in /sbin/init)

Sending DHCP requests ., OK

IP-Config: Got DHCP answer from 10.0.0.1, my address is 10.0.0.111 IP-Config: Complete:

     device=eth0, addr=10.0.0.111, mask=255.255.255.0,

    host=10.0.0.111, domain=, 
nis-domain=(none),

.....

The file system works fine on my MPC8266ADS board.

Do I have a problem with the mounting of the file system, or is there something wrong with my MMU?

The kernel is compiled with CONFIG_PPC_STD_MMU=y

Any suggestions about where i should start digging would be appreciated.

For Archive reasons I am postin the sollution to my problem.

The problem was a missing patch to the arch/ppc/kernel/cputable.c (got it from Montavista)
