Suddenly FW port stops working

[josh2007]

This happened just after loading newest OS 10.x.x to my MBP. (5.6?)

I bought the machine 3 weeks ago w/ warranty. Should I take it to Apple Store?

Yes. Test your firewire device on another computer, too.

Yes, you propably should take it to the Apple store in the end.

But first, have you tried the combo update? Try that first, as that might solve the issue if it was indeed the update that did you in.
