Hi, I did need to reboot my mythtv box a few days ago, and noticed some scheduled recordins were not recorded by mythtv. I digged into dmesg and found this: ivtv0: unable to open firmware v4l-cx2341x-enc.fw ivtv0: did you put the firmware in the hotplug firmware directory? ivtv0 warning: failed loading encoder firmware ivtv0 warning: Error loading firmware -3! ivtv0: Error -3 initializing firmware. ivtv0: Error -12 on initialization U few searches on the net showed me some steps to follow (like adding ACTION=="add", SUBSYSTEM=="firmware", RUN+="/sbin/firmware_helper" to the udev rules, but none of them fixed my problem. I remebered updating udev a while ago (and I did not reboot since then), so this might be the problem. The version which I have on my system now is udev-079-r1. But I already downgraded to 070-r1 and 068-r1 but none of them fixed the problem.

Upgrade to a newer kernel. There should have been some checks to prevent you from installing a bunch of those packages on such an old kernel. Maybe you have one configured in /usr/src/linux but are still running on old one.

I am using a Marvell SATA chipset, which does only work with 2.6.12 at this moment (kernel 2.6.15 has native support, but PIO mode only which is very slow). Is this an udev issue? I would love to downgrade to an older version which is working, but I can't find any on my gentoo system.
Ok, I tried upgrading my kernel to 2.6.15-gentoo-r1 (without raid, just for testing) and I receive the very same error message: ivtv0: unable to open firmware v4l-cx2341x-enc.fw ivtv0: did you put the firmware in the hotplug firmware directory? ivtv0 warning: failed loading encoder firmware ivtv0 warning: Error loading firmware -3! ivtv0: Error -3 initializing firmware. ivtv0: Error -12 on initialization ivtv: probe of 0000:00:0c.0 failed with error -12 What else can I try?
I reverted back to ivtv-0.4.0-r3 which works fine on both kernels.
I found that my /proc/sys/kernel/hotplug was empty. Putting /sbin/udevsend or /sbin/hotplug in there seemed to fix it for me.
Hi, I seems that ivtv-0.4.2 is depends on the hotplug package, so just do an: emerge sys-apps/hotplug and you are running ;) At least that's what got me running again.
(In reply to comment #6) > I found that my /proc/sys/kernel/hotplug was empty. Putting /sbin/udevsend or > /sbin/hotplug in there seemed to fix it for me. > Mine was already set to /sbin/udevsend. I emerged hotplug, and changed it to /sbin/hotplug, and things seemed to work now. I haven't restarted yet, but I will do so as soon as I possibly can.
So then this is fixed? Reopen if it's still an issue.
