Bug#311815: kernel-source-2.6.11: [powerpc] screen garbage when using matroxfb acceleration
Package: kernel-source-2.6.11
Version: 2.6.11-3
Severity: important
I'm using Sven Luther's unofficial kernels for ppc64
(http://people.debian.org/~luther/ppc64) on a IBM pSeries 630 Model 6E4
(Power4 processor), no virtualization enabled (no LPARs). The system has a
Matrox G450 card. It seems that framebuffer acceleration has unexpected
consequences, because when using it, the text in screen is displayed all
wrong, and the console is unusable. I still can reboot using Control+Alt+Del,
but little else.
Using fbset to disable the acceleration ("fbset -accel false") fixes
it. Booting with video=matroxfb:noaccel does the trick too.
