Bug#342053: DirectFrameBuffer crashes on PPC systems if HW accelerated drivers are used

 Known good : radeonfb, vesafb (or whatever x86 uses).

vesafb is not built on powerpc, and the laptop we had in extremadura used a
radeon chipset, altough of the R300 variety.

isn't "fbonly" the PPC equivalent to "vesafb" on i386?
I know claudio ciccani worked a lot on DFB's Radeon driver recently, so things may have been fixed in DFB 0.9.25.

 Known bad : atyfb, nvidiafb

when acceleration was enabled.
But that was with GTKDFB 2.0.9 and DFB 0.9.22, while now we have DFB 0.9.25 and GTK 2.8.20 and many bugs got fixed.

And it will be better with gtk 2.10.x even, right ?

On i386 this proved to be true, but i cannot speak for other archs as i never experimented anything personally.

This is the most serious bug affecting g-i on PPC, and i wasn't able to fix it because i have no PPC HW.

Yes, i will. Need to build a netboot g-i image and will test that on my
pegasos with the radon 9250 board.

If you experience crashes, you may want to run the d-i in a chroot cage, like explained in this [1] wiki page.

Sven, do you think can give the PPC g-i a try? i will help you on debugging it as much as i can.

Indeed, that is my intentions, a first test today, and more over the week-end.

thanks! Having the g-i avalable for PPCs too would be really nice!
