presumably nf_ct_helper_hsize is zero

I'd have thought that the same bug would be present in mainline - there's
nothing in git-net.patch.

Hi,
config the CONFIG_NF_CONNTRACK_AMANDA=m, reboot , still oops, but this
time the point is nf_conntrack_ftp_init, (I doubt the

boot with vga_ask and select 80x60, copyed more infomations:
---------pre oops:-----------
