Comment 12 for bug 1045047

Thanks Stefan!

Bought a new 4-to-6 FW cable.

Desktop - to TRV-900

On connection the bus reset loop starts running, nothing else
On disconnection I got this:

Desktop to laptop, both runnint Ubuntu 12.04:

This is what desktop gave on connection:

[ 689.580029] firewire_core 0000:06:03.0: rediscovered device fw0

Nothing on laptop.

I suppose this points to defect HW? Propably the (integrated) adapter on the desktop?
How easy are these things to break?

Will try older Ubuntu later.
