networking - NFS mount rootfs issues in ubuuntu 14.04 - Ask Ubuntu


i working on powerpc board using kernel 3.10, having issues mounting rootfs.

getting issue below

net: registered protocol family 17 ipv6: addrconf(netdev_up): eth0: link not ready ipv6: addrconf(netdev_up): eth1: link not ready ipv6: addrconf(netdev_change): eth0: link becomes ready sending dhcp requests .., ok ip-config: got dhcp answer 10.162.0.1, address 10.162.103.192 ip-config: complete:      device=eth0, hwaddr=00:10:ec:00:5c:5b, ipaddr=10.162.103.192, mask=255.255.0.0, gw=10.162.0.1      host=10.162.103.192, domain=mvista.com, nis-domain=(none)      bootserver=0.0.0.0, rootserver=10.162.103.21, rootpath=      nameserver0=10.162.0.5, nameserver1=10.0.0.5 vfs: mounted root (nfs filesystem) on device 0:10. devtmpfs: mounted freeing unused kernel memory: 144k (c0393000 - c03b7000) nfs: server 10.162.103.21 not responding, still trying nfs: server 10.162.103.21 not responding, still trying nfs: server 10.162.103.21 ok nfs: server 10.162.103.21 ok nfs: server 10.162.103.21 not responding, still trying  nfs: server 10.162.103.21 ok  nfs: server 10.162.103.21 not responding, still trying nfs: server 10.162.103.21 not responding, still trying

it stopping here , not responding, giving cmd line arguments as

root=/dev/nfs nfsroot=<server ip>:<root path> rw ip=dhcp

and not providing arguments in /etc/dhcp/dhcpd.conf target setup/mac address.

i had done nfs server setup based on ubuntu documentation , tried same setup other host pc, getting same error above. confirmed host setup fine nfs server.

this issue resolved changes in mac controller driver changes, 100mbps 10mbps, , protocol change udp tcp in fs/nfsroot.c , port no used nfs boot.
