Hello all,

Having some trouble setting up my new CMD649 based UDMA 100 ATA
controller under Linux. Every time DMA is enabled a kernel error =
message
like this is displayed:
hde: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func =
only: 14
hde: irq timeout: status=3D0x58 { DriveReady =
SeekComplete DataRequest }
hde: DMA disabled
I've altered the hardware configuration/cables etc and tried a few
patch levels with the latest being TEST9-PRE9. Same type of errors =
with
all configurations. The help screen for CMD64X in the kernel =
configurator
doesn't even include CMD649 (only CMD648 for example) so maybe this =
thing is
too new for Linux support? Anyway, I'd be happy to test any and all
patches sent my way......
