Hello,
im building a kernel for my db800 development board running with linux.
In short "words", here is the problem:
-----------------------------------copy-------------------------------------------------
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
AMD5536: IDE controller at PCI slot 0000:00:0f.2
AMD5536: chipset revision 1
AMD5536: not 100% native mode: will probe irqs later
AMD5536: 0000:00:0f.2 (rev 01) UDMA100 controller
ide0: BM-DMA at 0x1ca0-0x1ca7, BIOS settings: hda:pio, hdb:pio
hda: SanDisk SDCFH-2048, CFA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: max request size: 128KiB
hda: 4001760 sectors (2048 MB) w/1KiB Cache, CHS=3970/16/63, DMA
hda:<4>hda: dma_timer_expiry: dma status == 0x21
hda: DMA timeout error
hda: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: DMA disabled
ide0: reset: success
hda1
-----------------------------------/copy-------------------------------------------------
Here are some more information...
Full bootlog - http://nopaste.info/5498e6335b.html
Kernel .config - http://rootbox.de/kernelconf
Im very that it is a real sandisk, hdparm says the DMA is disabled. The
card supports MWDMA modes 0 to 2...
Does anybody have i idea what todo here?
Any tipps are very welcome :)

Steffen
