Sure. it would be preferable but unfortunately the PowerMac on-board IDE controller (CONFIG_BLK_DEV_IDE_PMAC), used for the DVD drive on B/W G3's, doesn't have a PATA equivalent. So it's pragmatic (until the IDE code is removed) to use the IDE cmd64x driver to minimise kernel code size. A minor correction to my previous post, the first version of Ubuntu to suffer from this problem was 9.10. -- Lawrence > > Cheers, > Ben. > > > diff -uprN a/arch/powerpc/configs/pmac32_defconfig > > b/arch/powerpc/configs/pmac32_defconfig > > --- a/arch/powerpc/configs/pmac32_defconfig 2010-05-16 23:17:36.000000000 > > +0200 > > +++ b/arch/powerpc/configs/pmac32_defconfig 2010-07-03 20:11:10.000000000 > > +0200 > > @@ -738,7 +738,7 @@ CONFIG_BLK_DEV_IDEDMA_PCI=y > > # CONFIG_BLK_DEV_AEC62XX is not set > > # CONFIG_BLK_DEV_ALI15X3 is not set > > # CONFIG_BLK_DEV_AMD74XX is not set > > -# CONFIG_BLK_DEV_CMD64X is not set > > +CONFIG_BLK_DEV_CMD64X=y > > # CONFIG_BLK_DEV_TRIFLEX is not set > > # CONFIG_BLK_DEV_CS5520 is not set > > # CONFIG_BLK_DEV_CS5530 is not set > > > > > > > > > > _______________________________________________ > > Linuxppc-dev mailing list > > Linuxppc-dev@lists.ozlabs.org > > https://lists.ozlabs.org/listinfo/linuxppc-dev > > -- -- Lawrence Rust _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
