Hi Yann
Yes this is a known problem.
Please try commit 3408404a4c2a4eead9d73b0bbbfe3f225b65f492 (inetpeer: Use correct AVL tree base pointer in inet_getpeer())
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3408404a4c2a4eead9d73b0bbbfe3f225b65f492
I believe David will send it to stable team shortly, if not already done :)
Thanks
