Re: Trouble compiling kernel for G5.

ide0, timeout waiting                   for dbdma command stop
ide-cd: dma error
hda: DMA disabled
hda: dma error: status=0x50 { DriveReady SeekComplete }
hda: dma error: error=0x00
cdrom_newpc_intr: 4 residual after xfer
cdrom_newpc_intr: 4 residual after xfer

And hdparm shows the drive to no longer have DMA turned on, which it did
before running growisofs.

The same command on a B&W G3 runs fine with DMA (2.4.23 kernel).

So, to answer your question, it seems it does not work, no.

Look like an underrun again, or an alignement problem as there
seem to be something weird with the DBDMA on the G5 at least
(there is some "workaround" code in darwin that I haven't been
able to understand fully yet).
