Post subject:	I broke my lircd config - SOLVED VIA CODE HACK
I've had a working lirc config for over a year. I have an RCA 6-in-1 remote and a homemade receiver. I have a custom lircd.config that was created via irrecord. I also have a custom keymap setup in mythweb with matching .mythtv/lircrd everything was working perfectly. I upgraded to the latest R5A release, installed lirc 0.7.1 and everything was still working perfectly.....but now nothing. I have 'touched' many things since the upgrade and since the remote was working so I dont know what I broke. I did play with mplayer (mythvideo) it was not recieving the IR signals. I played with many things included window manager focus. anything amiss below? any WM focus concerns? mode2 shows lots of output and irrecord seem happy.

can someone explain to me lirc_serial and lirc_i2c. within my dmesg I see this before ivtv loads: Code: lirc_dev: IR Remote Control driver registered, at major 61 BUG: using smp_processor_id() in preemptible [00000001] code: modprobe/2529 caller is init_port+0xb1/0x290 [lirc_serial] [<c028f15c>] smp_processor_id+0x8c/0xa0 [<e10b9a11>] init_port+0xb1/0x290 [lirc_serial] [<e10ba35a>] init_module+0x3a/0xa0 [lirc_serial] [<c01342a2>] sys_init_module+0x172/0x230 [<c0103017>] syscall_call+0x7/0xb lirc_serial: auto-detected active low receiver lirc_dev: lirc_register_plugin: sample_rate: 0 Linux video capture interface: v1.00 ivtv: ==================== START INIT IVTV ==================== then later I see Code: lirc_i2c: chip found @ 0x18 (Hauppauge IR) ivtv: i2c attach [client=Hauppauge IR,ok] lirc_dev: lirc_register_plugin: sample_rate: 10 The "Hauppauge IR" remote part bothers me. is lirc_i2c the Hauppauge module? do I need it if Im using a serial IR receiver. is this a Red herring?

Ok, continueing the conversation with myself (fell free to join in) seems that mode2 and irrecord both capture IR signals. iwr doesnt report anything. I was convinced that the i2c stuff was cauisng my pain. I did a Code: apt-get remove lirc then a configure, make and make install of lirc 0.7.1. still no joy! I'm stuck and I need some help. since lirc has always 'just worked' I dont fully understand how all of the pieces work.

I've been there. This will answer some (but not all) of your lirc questions. http://www.lirc.org/html/install.html#installing shplad khrusher wrote: Ok, continueing the conversation with myself (fell free to join in) seems that mode2 and irrecord both capture IR signals. iwr doesnt report anything.

For what it's worth, I had the exact same problem, researched for 4 days on several sites, tried reloading 8 times each with slightly different configurations all to no avail. The core lirc worked (irrecord did see the remote) but I could never get lircd to recognize the system... I also had an issue with mplayer (would not pass ac3 anymore to an external processor) even though I down-reved to mplayer-586 - same as my original R5A12. Finally I just went back to R5A12. I did discover that there seems to be a known issue with the 2.6.11 kernel and lirc 1.7.x (do a search on the error in your syslog (BUG: using smp_processor_id() in preemptible [00000001] code: modprobe). There seems to be a lot of people with serial IR receivers that are having problems getting them to work with this kernel. The following is from my last syslog before I went back to A12... lirc_dev: IR Remote Control driver registered, at major 61 BUG: using smp_processor_id() in preemptible [00000001] code: modprobe/2011 caller is init_port+0xb1/0x290 [lirc_serial] [smp_processor_id+140/160] smp_processor_id+0x8c/0xa0 [pg0+549513745/1067987968] init_port+0xb1/0x290 [lirc_serial] [pg0+549516122/1067987968] init_module+0x3a/0xa0 [lirc_serial] [sys_init_module+370/560] sys_init_module+0x172/0x230 [syscall_call+7/11] syscall_call+0x7/0xb lirc_serial: auto-detected active low receiver lirc_dev: lirc_register_plugin:sample_rate: 0

Thanx, that is my problem. did you downgrade lirc ot are there other fixes

I did try a downgrade of lirc but didn't help. I tried both 1.7.0 and 1.7.1 (as well as the flavor delivered in the build). I even found a comment somewhere that implied a problem because of mplayer - so I removed that - no good. I am convinced it is related to a kernel problem... With the number of people having this problem, I am sure there will be a solution soon. Right now I am running R5A12 with lirc 1.7.1, mplayer-586, and Alsa 1.0.8. It runs almost flawlessly (including AC3 passthru from mplayer without changes to my core configuration).

thanks for the posts, where did yo see others having issues, I dug though the lirc forums, not much there? where would /I watch of a solution? do you think the solution is a kernal patch otr a lirc patch?

An error in my last post - I am running LIRC 1.7.0 with R12 - LIRC 1.7.1 has a bug in it - can't get it to work with a serial receiver. Sorry What release are you running?

are tou sure those versions correct? im have 0.7.1 Code: root@mythtv:/usr/src # lircd -v lircd 0.7.1 maybe ill try 0.7.0 cecil, which version do you use on the distro?

Author:	khrusher [ Thu Jun 09, 2005 8:41 am ]

should I be surprized that I'm getting SMP errors on a single cpu box? did I read somewhere that the kernel is compiled w/ smp support. is that causing my pain?

Author:	Xsecrets [ Thu Jun 09, 2005 9:53 am ]
Post subject:
an smp kernel on a single processor box will spit out one or two error messages on boot saying it only found one cpu, but other than that it should not cause any errors.

Well, no help on the lirc lists, not much help of any kind over there...most posts remain without a single response. We knoppmythers are pertty lucky we have this active forum. my question is... what version do I need to rollback to to have a functioning remote via lirc_serial. I moved from R4V5 with a working remote to R5A16 badness.

Sorry for the delay khrusher - I took a few days off - no access (no TV, cable, email, Myth, etc...). I found a post somewhere about a problem with a serial IR Blaster that suggested something to try (in my office and don't have access to my box so I can't give you the specifics now). I am going to rebuild my test machine this week and try it. They, too, were having problems with 1.7.1 and down reved to an older LIRC release. They also tried a different sequence of events (and the moon was full and stood on one foot while chanting..). I will try it this week and report back. As posted earlier, I can attest to R5A12 working well and somewhat solid. Another requirement I have is mplayer passing AC3 thru spdif. I was never able to get that working with R5A16 either (one quirk is that I am using a SB 5.1 - that may be part of the problem with R5A16 since ALSA is somewhat particular with that card.).
