atyfb distortion on Beige G3

Bug #193724 reported by Risto Suominen on 2008-02-20
Affects Status Importance Assigned to Milestone
linux-source-2.6.15 (Ubuntu)

Bug Description

Binary package hint: linux-image-2.6.15-26-powerpc

In frame buffer mode, there are vertical lines where the characters rapidly change between the right one and another beside, making it difficult, or impossible, to read.

I'm running 6.06 LTS, the machine is a Beige Power Mac G3/233 (rev B), video controller is ATI 3D Rage II+, with full 6 MB of video memory.

This used to work in 4.10, at least on another similar (rev A, but practically same) machine.

(It's sad, how at least 3 things that did work at that time, have stopped doing it. At the same time, I haven't seen any areas where support for these oldies has become better. The 2nd one is an xorg problem already reported, the 3rd one is the ability to be booted with quik, maybe I should report that, too...)

This wont be fixed in dapper 6.06. Please test in a newer release.

status: New → Won't Fix

I tried with gutsy 7.10: same. Actually I was only able to boot the kernel, but that was enough for seeing the distortion. BootX crashed if I tried to add the initrd, maybe it has grown over some limit.
