With so much good development being done on framebuffer drivers at the mo= ment, perhaps the following is only a temporary problem, but I hope the following repor= t is of some use. I seem to be triggering a reproducible bug when loading rivafb, whether i= t is built-in or modular with both 2.5.54 & 2.5.55 ( and, I suspect, 2.5.53 also ). I have tried rivafb on 2 different nVidia cards, both yield the similar r= esults when using recent ( Jan 8 ) fbdev.diff.gz patch. After rivafb is loaded, the display goes bright green. After entering a c= ommand, I get text back, but colours are wrong - there is no visible blue on screen i.e= with colorized ls listing, normally blue text is bright green, normally red is ( brighte= r ) red, normally white is grey. This is from 2.5.55 with fbdev.diff.gz applied, rivafb and fbcon both mod= ular: I have manually insmodded cfbimgblt & vgastate, then insmod rivafb Jan 11 12:30:41 TBird kernel: rivafb: nVidia device/chipset 10DE002C Jan 11 12:30:41 TBird kernel: rivafb: RIVA MTRR set to ON Jan 11 12:30:41 TBird kernel: rivafb: PCI nVidia NV4 framebuffer ver 0.9.= 5b (nVidiaRIVA-VTNT2, 16 MB @ 0xD0000000) Jan 11 12:30:41 TBird kernel: Badness in kobject_register at lib/kobject.= c:129 Jan 11 12:30:41 TBird kernel: Call Trace: Jan 11 12:30:41 TBird kernel: [<d08d43b4>] rivafb_driver+0x54/0xfffddd00= [rivafb] Jan 11 12:30:41 TBird kernel: [<c01c6aa6>] kobject_add+0x56/0x60 Jan 11 12:30:41 TBird kernel: [<d08d43a4>] rivafb_driver+0x44/0xfffddd00= [rivafb] Jan 11 12:30:41 TBird kernel: [<c01f67f9>] bus_remove_device+0x59/0xc0 Jan 11 12:30:41 TBird kernel: [<d08d43a4>] rivafb_driver+0x44/0xfffddd00= [rivafb] Jan 11 12:30:41 TBird kernel: [<d08d3078>] +0x0/0xfffdefe8 [rivafb] Jan 11 12:30:41 TBird kernel: [<c01f6c51>] put_driver+0x31/0x40 Jan 11 12:30:41 TBird kernel: [<d08d4388>] rivafb_driver+0x28/0xfffddd00= [rivafb] Jan 11 12:30:41 TBird kernel: [<c01cb369>] pci_device_resume+0x49/0x60 Jan 11 12:30:41 TBird kernel: [<d08d4388>] rivafb_driver+0x28/0xfffddd00= [rivafb] Jan 11 12:30:41 TBird kernel: [<d08b2032>] 0xd08b2032 Jan 11 12:30:41 TBird kernel: [<d08d4360>] rivafb_driver+0x0/0xfffddd00 = [rivafb] Jan 11 12:30:41 TBird kernel: [<d08d5d00>] +0x0/0xfffdc360 [rivafb] Jan 11 12:30:41 TBird kernel: [<c012ca97>] load_module+0x117/0x1c0 Jan 11 12:30:41 TBird kernel: [<c0109327>] system_call+0x7/0xb Jan 11 12:30:41 TBird kernel: Module Size Used by rivafb 45444 0 cfbimgblt 2880 1 rivafb vgastate 9472 1 rivafb mousedev 7256 1 Now I rmmod rivafb and insmod it again : Module Size Used by cfbimgblt 2880 0 vgastate 9472 0 mousedev 7256 1 Jan 11 12:35:29 TBird kernel: Badness in kobject_register at lib/kobject.= c:129 Jan 11 12:35:29 TBird kernel: Call Trace: Jan 11 12:35:29 TBird kernel: [<d08d43b4>] rivafb_driver+0x54/0xfffddd00= [rivafb] Jan 11 12:35:29 TBird kernel: [<c01c6aa6>] kobject_add+0x56/0x60 Jan 11 12:35:29 TBird kernel: [<d08d43a4>] rivafb_driver+0x44/0xfffddd00= [rivafb] Jan 11 12:35:29 TBird kernel: [<c01f67f9>] bus_remove_device+0x59/0xc0 Jan 11 12:35:29 TBird kernel: [<d08d43a4>] rivafb_driver+0x44/0xfffddd00= [rivafb] Jan 11 12:35:29 TBird kernel: [<d08d3078>] +0x0/0xfffdefe8 [rivafb] Jan 11 12:35:29 TBird kernel: [<c01f6c51>] put_driver+0x31/0x40 Jan 11 12:35:29 TBird kernel: [<d08d4388>] rivafb_driver+0x28/0xfffddd00= [rivafb] Jan 11 12:35:29 TBird kernel: [<c01cb369>] pci_device_resume+0x49/0x60 Jan 11 12:35:29 TBird kernel: [<d08d4388>] rivafb_driver+0x28/0xfffddd00= [rivafb] Jan 11 12:35:29 TBird kernel: [<d08b2032>] 0xd08b2032 Jan 11 12:35:29 TBird kernel: [<d08d4360>] rivafb_driver+0x0/0xfffddd00 = [rivafb] Jan 11 12:35:29 TBird kernel: [<d08d5d00>] +0x0/0xfffdc360 [rivafb] Jan 11 12:35:29 TBird kernel: [<c012ca97>] load_module+0x117/0x1c0 Jan 11 12:35:29 TBird kernel: [<c0109327>] system_call+0x7/0xb Jan 11 12:35:29 TBird kernel: Module Size Used by rivafb 45444 0 cfbimgblt 2880 1 rivafb vgastate 9472 1 rivafb mousedev 7256 1 BTW1: With stock 2.5.5 and modular rivafb, module will not load, this is = what I get : Jan 10 12:49:53 TBird kernel: rivafb: falsely claims to have parameter fo= nt BTW2: the FBCON_ADVANCED "Advanced low level driver options" still shows= up in=20 make *config, but does not seem to do much - should it still be there ?

Loading fbcon causes bigger problems : serial OOPSes shortly followed by = complete lockup accel_putcs always seems to be implicated.
