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.
