Re: rivafb "Badness" using fbdev.diff.gz and 2.5.5[45]

[Jak <rfjak@eircom.net>]

James,
		I still see the same problem using 2.5.59. I think this
is the same problem as that referred to by Udo A. Steinberg
http://marc.theaimsgroup.com/?l=linux-kernel&m=104278873827538&w=2
( I get similar results as him if I compile rivafb built-in )

Is this possibly related to driver-model issues discussed in this thread ?
http://marc.theaimsgroup.com/?l=linux-kernel&m=104283662023857&w=2

Good news is that 2.5.59 seems quite stable as regards framebuffer.
It no longer locks up after loading fbcon. But rmmod fbcon still
causes instant death accompanied by increased whirring noises from inside
box.

To summarise:
 insmod rivafb causes "Badness in kobject_register" every time 
   ( after pci_register_driver() in rivafb_init(),see below )
 after insmod rivafb, I have a green screen, which can be cleared by fbset
  ( fbset now changes resolution of all VTs, this is different from 2.4.x )
 after clearing green screen using fbset, text colours are wrong
 now ( 2.5.59 ), I can insmod fbcon, and screen looks OK again ( apart from
  the left-hand-most column of screen appears at right-hand side of screen )
 rmmod fbcon locks up machine, no ALT-SYSRQ effective
