kernel hangs when powering up DV-camera

[Marcel J. <mph...@ho...>]

Hi,

This is my first try with ieee1394 and I seem to get my card going.
My card is a Texas Instruments OHCI campliant one and I use kernel 2.4.0 with 
the CVS fix (05-02-2001).

When I leave the camera switched off, the modules load fine. When I power up 
the camera, my whole box hangs (no mouse/keyboard/network etc). No matter if 
I first load the modules and power up the camera afterwards or the other way 
round.

I've got no idea where to start looking for a solution. Since my box locks 
immediately after switching on the camera, I have no report to my log files.

I included the kernel log of my modules (when camera switched off) at the 
bottom of this mail.

My camera is a sony DCR-PC5E.

Can the use of devfs be a problem ?

thanks,
Marcel Janssen
