Public bug reported: This happens in 16.04 LTS dailyimage (2016-02-08). /etc/modules is copied from 14.04 LTS (and works there). My /etc/modules:
# /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. loop lp rtc bonding 8021q ip_gre nf_conntrack hashsize=262144 nf_conntrack_ftp ports=21 nf_conntrack_pptp nf_conntrack_netbios_ns nf_nat_ftp nf_nat_pptp act_mirred sch_fq_codel ifb numifbs=4 It looks like ifb numifbs=4 is ignored, when I remove numifbs=4 then all is OK, module is loaded with default 2 devices. When I type modprobe ifb numifbs=4 from console all is OK, module is loaded. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1543183 Title: /etc/modprobe ignores ifb numifbs=xx To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1543183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
