Hi all We are porting linux 2.6.24 on a board with powerpc processor and with AMD 79C972 ethernet chip Thru ramdisk I can able to boot the board and i can do the ifconfig eth0 up.. When I try to boot the board with nfs iam getting the following NET: Registered protocol family 1 NET: Registered protocol family 17 RPC: Registered udp transport module. RPC: Registered tcp transport module List of all partitions: No filesystem could mount root, tried: ext3 ext2 msdos ntfs Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0) Rebooting in 180 seconds.. 1. In the kernel the nfs related configs are enabled properly 2. The nfs server and file system is proper( I have mounted and checked the nfs server & file system thru another working setup) 3. The ethernet driver pcnet32.c under drivers/net is okkk it seems becaz it is working when i boot the board thru ramdisk Please shed me some light where to look and what may be the reason iam getting the above error when i boot thru NFS Thanks in advance
