[support] Need help in kernel crash in MR.

[satya sahu]

Hi all ,


I  am facing a problem while setting up ipv6-ipv4 network using UMIP0.4 and
kernel version-2.6.24. kernel panic occured while switching between ipv6
network to ipv4 network(frequently occurs).

while debugging i found that it is in kernel ipv6 routing part (dst_destroy
symbol in kernel). for detail stack strace please find the attached
kernel_panic file.


UMIP0.4 and kernel -2.6.24 is pacthed against the instruction given in
http://perso.crans.org/kiennd/Mobinet/Readme.DSMIPv6 and
http://perso.crans.org/kiennd/Mobinet/README.


Any information regarding this highly appreciable.
