Hi again Michael,
I more or less found the bug I was encountering at begeistert (black
screen after bootup using nvidia driver).
It turns out it's the fact that AGP gets enabled. From the looks of it
this wasn't a problem before the USB changes, while afterwards this is a
problem.
Could it be that the AGP aperture is somehow accidententally used for
mapping files? That would explain the 'random' behaviour I see here:
system can work, but if I add one file to the running image on stick, on
the next boot the screen is black, and if I delete it again, things are
working again..
I tested an image from 12 september: all OK. Image from for instance 10
november: trouble. If I copy the nvidia driver and agp busmanager from the
10 november image onto the 12 september image: all OK. Other way around:
trouble.
Could you (or Axel) doublecheck for AGP/memory mapping trouble??
Thanks!!
Rudolf.
