[Bug 596828] Re: Won't connect to DVD writer

[Michael]

I tried to build a new kernel by following the instructions but I got no
options on the kernel I would be using and the machine got a kernel
panic so I had to rebuild from scratch.  I guess I did something wrong!

I've just upgraded to the latest ubuntu kernel and am still getting the
error.

I have also tested the same dvd reader / writer on two other ubuntu
installs with pretty much the same problem.  But it still works fine on
windows

Here's the latest
