From 70093cfde8af52b0b9030d90f9004cbde38f2ff8 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Tue, 27 Mar 2007 01:36:50 +0200 Subject: ieee1394: eth1394: don't autoload by hotplug when ohci1394 starts Until now, ieee1394 put an IP-over-1394 capability entry into each new host's config ROM. As soon as the controller was initialized --- i.e. right after modprobe ohci1394 --- this entry triggered a hotplug event which typically caused auto-loading of eth1394. This irritated or annoyed many users and distributors. Of course they could blacklist eth1394, but then ieee1394 wrongly advertized IP-over- 1394 capability to the FireWire bus. Therefore - remove the offending kernel config option IEEE1394_CONFIG_ROM_IP1394, - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was loaded. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 . To emulate the behaviour of older kernels, simply add the following to to /etc/modprobe.conf: install ohci1394 /sbin/modprobe eth1394; \ /sbin/modprobe --ignore-install ohci1394 Note, autoloading of eth1394 when an _external_ IP-over-1394 capable device is discovered is _not_ affected by this patch.
