[mythtv-users] lirc and irrecord die with: irman_init(): Unknown error 4294967293

[Ali Asad Lotia]

Hello All,
I know that this may be OT, but I've seen other lirc related posts on
this list and am sufficiently desperate. Please accept my apologies if
this is OT enough to be annoying. I initially posted this to the lirc
list, but have not received a response yet and am hoping that a fellow
mythtv user may have seen something similar and fixed it.

I am currently trying to set up lirc with a IRA-3 receiver that i
purchased from Home Electronics
(http://www.home-electro.com/ira3.php). The receiver is hooked up to
serial port 1 (ttyS0) and when I cat /dev/ttyS0, i can see it print
output to the screen when I send it commands from a Radio Shack
15-2116 remote control.

I have installed libirman-0.4.3, which I compiled from source after
applying the patch for IRA-3 devices that Pratap Pereira release on
this list (http://sourceforge.net/mailarchive/message.php?msg_id=10826076).
I am running Gentoo and the kernel is 2.6.12-gentoo-r9. The serial
driver is compiled into the kernel. I installed lirc-0.7.2 using the
Gentoo ebuild and did pass options to build the irman driver when
installing.

When I try to run irrecord, it quits with the following message
kubrick usr # irrecord -d /dev/ttyS0 -H irman test

irrecord -  application for recording IR-codes for usage with lirc

Copyright (C) 1998,1999 Christoph Bartelmus(lirc at bartelmus.de)

irrecord: could not init hardware (lircd running ? --> close it, check
permissions)

The output to syslog is:
Aug 27 02:33:19 kubrick irrecord: could not open /dev/ttyS0
Aug 27 02:33:19 kubrick irrecord: irman_init(): Unknown error 4294967293


When I run lircd, it starts up but quits as soon as I run irw.
kubrick sbin # ./lircd -n -d /dev/ttyS0 -H irman
lircd-0.7.2[13068]: lircd(irman) ready

running irw crashes lircd

lircd-0.7.2[13068]: accepted new client on /dev/lircd
lircd-0.7.2[13068]: could not open /dev/ttyS0
lircd-0.7.2[13068]: irman_init(): Unknown error 4294967293
lircd-0.7.2[13068]: caught signal

I am running as root so permissions aren't a problem. Particularly
since I can get output on the same serial port by just catting the
device (as mentioned above).

Machine specs:
P4 3.2 ghz
2GB RAM
Gigabyte GA-8I945P Pro motherboard
Gigabyte GeForce 6600 256MB vga card
Hauppauge PVR-500 tv tuner card
Alink+ Atheros based PCI wireless card
2 x 250gb Hitachi SATA-2 HD
NEC ND-3520 DVD burner
ASUS 16x DVD-ROM
Antec NeoPower 480 PS

I'm using the one and only serial card on the MB and its irq settings are
ttyS0 at I/O 0x3f8 (irq = 4)

I am attaching my kernel .config file to this message. I am running
the NVIDIA binary graphics drivers (v 1.0.7676).

This is the last missing bit thats preventing my MythTV machine from
being rolled out into the TV area. I would be hugely grateful if some
kind soul were to help me get lirc working.

Thanks
Ali
