Perfect. I found the problem and I'm about to commit to BK. I posted the latest patch against 2.5.49 at http://phoenix.infradead.org/~jsimmons/fbdev.diff.gz > I understand this situation perfectly, looks like it's almost common for > developers working in "not so importatnt for servers" subsystems :( :-( Some day that attitude will change. P.S Several drivers have been ported but not all. NVIDIA is still broken but I will fix it tonight. |

I have a 01:00.0 VGA compatible controller: ATI Technologies Inc 3D Rage Pro AGP 1X/2X (rev 5c) and use this in lilo.conf: image=/boot/2.5.49fb label=2.5.49fb append="video=atyfb:1280x1024-16@85" This got me a 160x64 framebuffer with yellow text on blue background. Nice, but only got about 10 lines before the kernel hung. The disk light got stuck on and there were no response to things like sysrq. The few lines displayed was about the fb, drm, and finally the 3com network adapter. Then nothing more. 2.5.49 without this patch works. I use devfs & preempt, the machine is UP and I use gcc-2.95.4 for compiling. Helge Hafting |

Are you using a PPC or ix86 box? I will test this tonight. > This got me a 160x64 framebuffer with yellow text on > blue background. Nice, but only got about 10 lines before > the kernel hung.

aty128fb works for me here with:
01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 PF/PRO AGP=
4x TMDS
Thank you!
There are a few glitches, but I've been unable to pin down
anything serious as the fbdev patch's fault. I'm still playing with
things (like Antonio Daplas' patches). I'll give a more full report
later.
FWIW, the fbdev patch applies with a few minor offsets to 2.5.50
except for the attached patch, which I extracted from bk. So if you
apply this patch in *reverse* to a clean 2.5.50 tree, the fbdev patch
should then apply okay (patch complained about a reversed hunk in
fbcon.c, but it should be harmless, I think.)

I noticed. My new patch fixes that. |
