Hello,

i am experiencing a panic whose logs are attached (grabbed with netconsole).

They look quite similar to what has been described here
    http://www.spinics.net/lists/linux-net/msg17689.html

The patch proposed as the solution (commit 
6b1e960fdbd75dcd9bcc3ba5ff8898ff1ad30b6e) seems to be applied (even with 
small differences) but the problem persists.

The kernel is a debian linux-image-3.2.0-2-amd64 version 3.2.12-1

Any hint ?
I have checked the changelog of 3.2.13 and 3.2.14 and it doesn't seems 
to be any commit regarding such problems.

Thanks Eric,

is there a way to prvent those panics, meanwhile ?
I mean: i don't understand if it depends strictly on IPv6 or it has

The same kernel with ipv6 enabled but without ipv6 is not actually 
panic-ing ...

And thanks to Peter as well.

Massimo
