New firewire stack not working reliably for TI TSB82AA2 PCIE adapter

[manoj.iyer at canonical.com]

I see a couple of patches that went out for the device, sometime this 
weekend I will build a kernel with those patches for you to try, I will 
post links to your bug. Lets see if that fixes the issue for you.
