IrDA connection : IBM Thinkpad T21 / Palm m505
>Description:
Once IrDA support is enabled, you can use or not a ir transmitter.
If you use it, connection works else system can freeze.
>How-To-Repeat:
Of course first enable IrDA support in the BIOS:
* enable IrDA support in the kernel
irframe* at oboe?
irframe* at uirda?
irframe* at ustir?
pseudo-device irframetty
* enable IrDA support in the userland
set "irdaattach=YES" in the /etc/rc.conf file
* add the following lines in the /etc/rc.local file
if [ -f /usr/pkg/bin/irs ]; then
/usr/pkg/bin/irs -c -m 115200 -Y -y /dev/ptyqf
fi
* reboot the system
Now if I don't use ir device and I want to disable irdaattach daemon, system freezes.
I precise 3 things :
* that bug don't work everytime.
* i've just tested on NetBSD -current.
* if i use a Ir device (by exemple, my Palm m505) so i have no problem.
>Fix:
No fixing at this moment. Just kill the irs application before to shut down the system.
