@xabih your issue is NOT the one I have reported here, I suggest you open your own thread as should @Maverick1024 so as not to confuse things. Any fix for my issue will likely NOT resolve your problem.

@xabih I just noticed you have opened your own thread, now you need to remove your post in this one please.
In case anyone else finds this the issue is with the firewire_ohci and adding a module blacklist to grub allows the system to boot OK. My motherboard has a firewire interface on it, it’s not an addon card. Now to find out why!
