lirc problem- device node disappeared

So, about a week ago while I was in the middle of watching a recording in mythtv my machine completely locked up solid-- first time that's happened to me, the machine has been up & running for a year or so. After resetting it, everything seemed normal, but the remote no longer worked (remote has worked fine for several months). I found that the device node is not being created (normally it is /dev/lirc/0). All I see now is...

no ideas at all?

I'm having the same problem. /etc/conf.d/lircd still has the option listed correctly too.

EDIT:

Have you recently upgraded to the 2.6.20-series kernel? I just did since it went stable, and mythtv seems to have lost all of my scheduled recordings and I have the device node problem. When I boot into my old 2.6.19-r5 kernel all is well.

I very recently had a similar problem to this where the node seemed to suddenly randomly disappear; and tried re-emerging everything I could think of but to no avail.

Eventually, I managed to get my /dev/lirc/0 node back by running depmod -a after re-emerging lirc. I also had to put lirc_dev and lirc_i2c in my /etc/modules.autoload.d file because (I think) udev wasn't loading them properly.

I'm a relative newbie but I thought that depmod -a was run by the emerge script? Anyway, the above procedure worked for me and my lircd seems quite happy. btw, I'm running kernel 2.6.20-r9 and also using the ir blaster module from http://www.blushingpenguin.com/mark/blog/?p=24.

depmod -a didn't help for me.

I upgraded from Kernel 2.6.21-r3 to 2.6.22-r1, rebuilt lirc.

modprobe lirc_dev and lirc_i2c works quite well. Also dmesg shows something like:

same problem here with kernel 2.6.20-r8. Anyone found anything please? :/

Ok, I found the solution:

make oldconfig didn't shift the complete config of kernel 2.6.21 to 2.6.22.

I was really surprised, when I recognized that my IR-device wasn't found in dmesg. Then I found out, it didn't even recognize the whole tv card. So I looked into the kernel config, reactivated my tv card and enjoyed having my lirc device back.

Hopefully this was the only thing that oldconfig forgot to do.

I have a similar problem after upgrading to lirc 0.8.2 and to kernel 2.6.22.

I tried putting this into /etc/conf.d/lircd, but to no avail:
LIRCD_OPTS="-d /dev/lirc/0 "

I have a pctv remote, which doesn't require kernel modules, so I don't think the solutions mentioned in this thread are valid in my case...

Same problem here with the pctv pro. The TV tuner works perfectly but the remote stopped working after updating something (I don't know exactly what. lirc 0.8.2-r1?) Besides,

I have not applied this patch yet ... but supposedly this is an answer for those of us using serial IR.

http://www.nabble.com/%22setserial--dev-ttyS1-uart-none%22-broken-in-2.6.22--tf4219669.html#a12098479

I applied this patch and now all is good.

So I am using the latest kernel and the latest lirc

Well, I just updated the system, and found my remote not working (Pinnacle PCTV one connected to serial port). Now, before update I had lirc-0.8.1 here. It worked with gentoo-sources-2.6.22-r2 like a charm. The update took lirc up to version 0.8.2-r1. After this, it stopped working. Then I downgraded to 0.8.1 and the remote works again. So, I think the culprit in this case is lirc, not the kernel. Try downgrading to lirc-0.8.1, I think it could help some of you out here. Let me know if this helps some of you

P.S.
Is it just me or http://gentoo-wiki.com/Lirc is a bit outdated?

Hi everybody!

I have a Pinnacle Hybrid PCTV Pro PCI and I'm having trouble setting up de IR remote.

I'v tried with the dev/input driver on /dev/input/event6 (cat /proc/bus/input/devices tells me it's the ir receiver) and with the pctv driver on /dev/ttyS0-3 to no effect.

both irecord and irw seem to work but they don't get any key from the remote. And I know the remote is working because the TVset LED blinks to the IR

I tried to downgrade to lirc-0.8.1, no luck either.

I've never seen a /dev/lirc/0 ...

Could someone with this remote (I think it's the same as in the 310i...) please tell me if there is any other way or if i'm doing something wrong?

I'm using gentoo-sources-2.6.22-r8.

Many thanks,

Jakomo

This is probably a shot in the dark but today i updated to gentoo-sources-2.6.22-r8 and my remote went away as well (using the remote attached to my PVR-150). Even after module-rebuild rebuild. So i emerged lirc (cause /lib/modules/mykernelverssion/misc/lirc*) didn't exist, i also tried adding it manually to module-rebuild (it said it already existed). modprobe lirc_dev, lirc_i2c did nothing (i think because i have to restart lircd), in anycase after a reboot it all came up fine again.

Well I've rebooted many times and still can't get neither cat /dev/input/event6 nor irrecord nor irw showing anything when I press buttons...

BTW, I'm on AMD64, do you think it might have anything to do with this?

Thanks,

Jakomo

OK... update...

Although it doesn't make much sense, after unpluging everything (for totally unrelated reasons), enabling serial support in the kernel (which I hadn't :oops:

) and disabling the onboard serial port on BIOS (why not, could be be a resource conflict, right?), I finally got something to show up in cat /dev/input/event6 when I press buttons

However it doesn't happen often (most times I press buttons and nothing happens) and when it does it's quite delayed to the button presses.

After starting lircd, irw doesn't get anything and irrecord bails out saying "irrecord: gap not found, can't continue" Sometimes irrecord startes showing some dots but the end result is the same.

I think you're probably beyond what i can do to help, IIRC irw should output the remotes commands, do you get sluggishness in irw?

I already posted this in another thread, maybe one of you has a clue what's going on:

I have a very similar problem here. My mouse freezes while watching movies. It turned out that this was caused by the lirc support in mplayer. I usre the devinput driver for my Hauppage HVR1100.
