Hello,
I have a kernel bug with archlinux 64 & kernel 2.6.35.8-1 (all 2.6.35 ?)
This bug come when i stop (halt) a container.
I don't have this bug with kernel26-lts 2.6.32.25-2
I don't have this bug with kernel26 2.6.35.8-1 without modules nf_conntrack*
Can you help me ? I'm just a linux user.
Sorry for my english, i'm french. Christian.
