Re: No console anymore. How to figure this out.

Hi Dale,

I have been following your debugging and can't help directly, but I did 
happen to notice that someone shared a custom "soft scrollback" kernel 
patch to the user list, and I think they had mentioned you were one of its 
users. Is that patch still in your kernel and could that possibly be what 
is causing this issue?
