Somethings I compiled the Linux network modules (especially bridge and netfilter) without optimization, the kernel always crashes because of exhausted kernel stack. The similar problem has been discussed in http://lists.linuxfoundation.org/pipermail/bridge/2005-January/004402.html Is it OK the double the x86_64 kernel stack size?
