Subject: Oops with latest (netfilter) nf-next tree, when unloading iptable_nat
Date: Tue, 11 Sep 2012 11:51:21 +0200 [thread overview]
Message-ID: <1347357081.3928.32.camel@localhost> (raw)
Hi Pablo,
I'm hitting this general protection fault, when unloading iptables_nat.
Git tree: git://1984.lsi.us.es/nf-next
At commit 0edd94887d19 (ipvs: use list_del_init instead of list_del/INIT_LIST_HEAD)
Notice, I'm not seeing this with net-next (at commit 9f00d9776bc5b)
