IRDA under 2.6.5 gentoo kernel

I have kernel 2.6.5-gentoo-r1 and irda-utils-0.9.15 but irda doesn't work, I have found this in syslog:

May 23 01:34:29 dumi irattach: irattach: tty: set_disc(11): Bad file descriptor
May 23 01:34:29 dumi irattach: Stopping device /dev/ttyS1
May 23 01:34:29 dumi irattach: ioctl(SIOCGIFFLAGS): No such device
May 23 01:34:29 dumi irattach: exiting ...

Under kernel gentoo 2.4 it works fine. I use UDEV, and IRDA connected to mother board via 5 pin connector.

Any suggestions?? Thanks for every answer.

Hi,

I just have the same problem, and finally found the solution:

first, determine what is your irda chip (findchip is your friend here).
Then, recompile it in your kernel, as a module or not, as you whish.

Be sure that this chip has been recognized on startup. dmesg should tell you that irda0 devices has been created (it don't appear under /dev).

On my system, I then had to do irattach -s irda0 (without the /dev), and then modprobe ircomm-tty, and everything went fine, and I was finally able to synchronise my palm using IRDA.

Hi

Thank you very much.

Your advice didn't help me but when I was trying it I found another solution. I tried to use findchip but with no success as well as under 2.4 kernel because findchip was looking for FIR devices (which I don't have). But when I looked in 2.4 kernel config I've noticed that I forgot to compile Irtty (which is SIR) driver to my 2.6 kernel. With this driver IRDA works fine. Thank you. Have a nice day.
