Thanks. I realized it was going to be hard either way if the boot hangs
before I get to a command prompt, which was what was happening
yesterday.
I had to boot ubuntu to debug a sound issue, and it was very tricky
since most of the time it hung before I got to a command prompt, but I
was finally able to get it to work long enough to debug the sound issue
and go back to my self built kernel to port over the sound config I
needed.
I wish I could tell you exactly how to reproduct this in a more useful
way, sorry about that.
Marc
