PowerPC kernel linux-2.6.29.6 PANIC's at include/linux/cred.h for ipsec enabled kernel

Fri Aug 14 15:08:59 EST 2009

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.
Freeing unused kernel memory: 184k init

Any suggestions or the filed bug report anywhere ??
