mode2 works, irw doesn't

[Tilo L. <Til...@gm...>]

Hi

I have some problems with lirc and I'm unable to track them.
I use Opensuse 11.0 with self compiled kernel and latest lirc version.
I have connected a selfbuild receiver to /dev/ttyS0.

Sometimes lirc is working, sometimes not and I wasn not able to find  
the reason.

mode2 is working without problems. As soon as a button is pressed on  
the remote
there are logs on the screen. When lirc is started and irw is run it  
doesn't  show
any pressed key.

The next key after a reboot lirc is suddenly working as expected and  
irw shows the
pressed keys. The next day it doesn't work anymore.

Here is output of dmesg:

^^^^^^
Shouldn't I get a device busy here because /dev/ttyS0 is used?


FILE:~ # irw


And now nothing happens.



What should I do?

Best regards, Tilo
