Hi all, Target : PowerPC440 Kernel : Linux-2.6.29.6
The issue still remains in kernel linux-2.6.29.6 enabling following options in kernel, the kernel panics and won't boot anymore The following kernel options enabled : # Networking support CONFIG_NET=y CONFIG_INET=y CONFIG_NET_KEY=y CONFIG_XFRM_USER=y CONFIG_INET_AH=y CONFIG_INET_ESP=y CONFIG_INET_IPCOMP=y CONFIG_INET_TUNNEL=y # IPV6 CONFIG_IPV6=y CONFIG_IPV6_TUNNEL=y CONFIG_INET6_AH=y CONFIG_INET6_ESP=y CONFIG_INET6_IPCOMP=y CONFIG_INET6_TUNNEL=y # Cryptographic API CONFIG_CRYPTO=y CONFIG_CRYPTO_HMAC=y CONFIG_CRYPTO_NULL=y CONFIG_CRYPTO_MD5=y CONFIG_CRYPTO_SHA1=y CONFIG_CRYPTO_DES=y CONFIG_CRYPTO_AES=y CONFIG_CRYPTO_DEFLATE=y and while bootup I am seeing the panic/crash message as : Looking up port of RPC 100005/1 on 10.50.21.151 VFS: Mounted root (nfs filesystem) on device 0:13.
