(I don't have a log, this is just rewrite from screen: EIP: irda_device_set_media_busy+0x15/0x40 [irda] ali_ircc_sir_receive+0x4a/0x70 ali_ircc_sir_interrupt+0x66/0x70 ali_ircc_interrupt+0x5e/0x80 ..... ) When I turn debug on, I get just Assertion failed! net/irda/irda_device.c:irda_device_set_media_busy:128 self != NULL The obvious reason is that I don't have irlap module in that inits dev->atalk_ptr, so I'm getting assertion exception in irda_device.c:489.
