Description of problem: rhgb had flipped to show the problem text screen {for sendmail}. Just before networking line on the screen, the fatal message was shown. Also further down in the boot it repeated. Version-Release number of selected component (if applicable): initscripts-8.53-1 {fc6+updates+upgrade>f7t4} How reproducible: each time it boots. Steps to Reproduce: 1. bootup f7t4 Actual results: "fatal: module off not found" Expected results: "" Additional info: Appears to be inconsequential = unwanted noise ? during boot
Created attachment 153732 [details] serial console boot showing the location timing of the message While the machine is close to fc6 default, there was one mod performed: disabling ipv6, according to http://fedorasolved.org/network-solutions/disable-ipv6 In /etc/modprobe.conf: if neither net-profile-10 nor ipv6 are included: ok if net-profile-10 included: ok if ipv6 included: error if net-profile-10 and ipv6 are included: error With both included, ipv6 doesn't get loaded {ifconfig}. The error may be due to some other application attempting to load ipv6.
You should not use alias XXX off; you should use 'install XXX /bin/true'. The docs you referred to are wrong.
Unfortunately, the same info is provided by many sites. in modprobe.conf: Adding just the single: install ipv6 /bin/true is successful at disabling ipv6 {ifconfig}. Knowing what command line to put in /etc/modprobe.conf, it is much easier to find the same answers: http://www.fedoraforum.org/forum/showpost.php?p=244155&postcount=4 {still do the NETWORKING_IPV6=off and service disable for ip6tables}
Note that NETWORKING_IPV6=no has no effect - it needs to be done in modprobe.conf or /etc/modprobe.d.
