FWIW, I don't own any firewire devices, I only compiled the stack to see if the port was recognised by the kernel. So nothing has ever be connected to that port. I haven't reproduced the problem so far without the drivers compiled in (and with the debug option you suggested). I'll post some more info in a few days. > -- > Stefan Richter > -=====-==--- =-== ==-=- > http://arcgraph.de/sr/ > Regards, Fabio
