[Bug 46549] kernel panic when using infra red

Thu May 25 11:28:26 UTC 2006

Public bug reported:

Binary package hint: linux-image-2.6.15-23-686

After I upgraded to the latest dapper kernel I can not use the infrared.
I was using the irda-utils package and successfully using  irattach and
ircp to transfer the files to my cell phone with 2.6.15-22-686 kernel.
However with the new kernel whenever I try to use irattach the machine
hangs up. The error message is :

May 25 03:57:25 localhost kernel: [4295036.682000] irlap_change_speed(), setting speed to 9600

After this the machine just hangs.  the command I am specifically using is:
sudo irattach /dev/ttyS1 -s 

Also the system also hangs if irda-utils are allowed to stat during boot
up.

       Priority: (none set)
         Status: Unconfirmed
