Subject: Oops in 2.6.0-test[89] in tcp_v4_get_port (kernel with IPv6 enabled)

:

I just encountered a oops with kernels 2.6.0-test8 and -test9 (system
freezes the hard way, not even magic-key works). Problem does not exist
in 2.4.20.

:

I found a thread about similar issue in the archive
(thread subject: "oops in inet_bind/tcp_v4_get_port"). Yoshifuji Hideaki 
  provided a patch but unfortunately it causes some problems with 
ip_nat_helper and ip_nat_cores modules compilation (duplicate functions 
definitions)...

Please try the latest bk tree (with IPv6 enable, of course).  Thanks.
