Hi,

[1.] One line summary of the problem:

Kernel oops after unloading nf_conntrack_netbios_ns module

[2.] Full description of the problem/report:

After I remove the netbios-ns conntrack module,the kernel runs into an oops
when it tries to delete the appropriate conntrack entry. The problem is
reproducable, see the script below [7.]. My system has a Core2Duo processon,
probably this problem is SMP related problem.

[3.] Keywords (i.e., modules, networking, kernel):

modules, networking, netfilter, conntrack, netbios

[4.] Kernel information
[4.1.] Kernel version (from /proc/version):

Linux version 2.6.20-1-686 (Debian 2.6.20-3) (waldi@xxxxxxxxxx) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) #1 SMP Tue Apr 24 21:52:11 UTC 2007

[4.2.] Kernel .config file:

...

[5.] Most recent kernel version which did not have the bug:

Debian 2.6.18-4 (ip_conntrack_netbios_ns module)

So it's a regression.

[6.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

ksymoops seems to have gone and hidden the actual EIP decide from us.

ksymoops is no longer necessary as long as CONFIG_KALLSYMS=y. Are you able
to send just the raw oops message from dmesg please?

This architecture has variable length instructions, decoding before eip
is unreliable, take these instructions with a pinch of salt.
