Description Quentin Armitage 2012-10-26 17:48:38 UTC 
Description of problem:
There is a Kernel oops when ipv6 forwarding is enabled

Version-Release number of selected component (if applicable):
kernel-kirkwood-3.6.2-2.fc18.armv5tel

How reproducible:
Always

Steps to Reproduce:
1.Have at least two interfaces with global ipv6 addresses (the problem doesn't occur with ony one global ipv6 address)
2.echo 1 >/proc/sys/net/ipv6/conf/all/forwarding
3.Wait for some network traffic to arrive
  
Actual results:
Oops - see below for details

Expected results:
Packets successfully forwarded

Additional info:
This problem also occurs with the 3.6.1-1.fc18.armv5tel kernel. It does not occur with a homespun 3.4.7 kernel, which sucessfully routes ipv6.

The 3.6.2-2 system runs fine, handling ipv4 routing and generating and responding to ipv6 data. It is only when ipv6 forwarding is enabled that the oops ocurrs.

[ 1000.696510] Kernel panic - not syncing: Fatal exception in interrupt
Comment 1 Peter Robinson 2013-02-05 15:03:22 UTC 
Can you retest with the 3.7.x kernel series.

Please also provide details of the hardware and network interfaces

The problem appears to be resolved in the 3.7.5-201.fc18.armv5tel.kirkwood kernel.

For information, the hardware was a Dreamplug with the traffic attempting to route in and out on different vlans on the same physical interface.
