New firewire stack not working reliably for TI TSB82AA2 PCIE adapter

[manoj.iyer at canonical.com]

How often to do you see data corruption?

Can you please open a bug using the following command ?

$ ubuntu-bug linux

That will collect all the logs and fire up a web browser to launchpad, and 
you can add additional information there. Once you have that bug open 
please reply your bug number, and that will help us take a look at your 
problem.


Cheers
