After struggling to get this fixed, this is a workaround at least for
me on gentoo. I know that by putting /sbin/hotplug in
/proc/sys/kernel/hotplug would allow the firmware to be found and load
correctly. I didn't want to have to keep manually doing this
everytime I rebooted. More importantly, my wife didn't want to have
to keep doing this everytime she started the computer. Thus, I made a
really piss-poor init script for Gentoo. Granted, I'm not a
programmer and claim no ability to do so, but this script seems to
work ok for me. I have it changing /sbin/udevsend to /sbin/hotplug
and then loading ivtv and then changing /sbin/hotplug back. It looks
like it is loading before coldplug so other modules will load
properly. Anyways, here is the script:
-----------------------------Start script---------------------------------
#!/sbin/runscript
depend() {
# Call to load before coldplug
before coldplug
}
start() {
# display to the user what you're doing
ebegin "Starting IVTV drivers"
#change /proc/sys/kernel/hotplug
echo /sbin/hotplug > /proc/sys/kernel/hotplug
modprobe ivtv
#change it back
echo /sbin/udev_run_hotplugd > /proc/sys/kernel/hotplug
# output success or failure
eend $?
}
----------------------End Script----------------------------------------------
Hope this helps someone until a better fix is found. Still can't
figure out why udev doesn't work with hotplug to load the firmware and
it seems that noone else knows either. Wish udev had better logging
capibilities so it would be easier to debug.
