Hello,
I got the following error for 3 of my 4 harddrives:
hde: dma_intr: status=0x51 { DriveReady SeekComplete Error } hde: dma_intr: error=0x84 { DriveStatusError BadCRC } hde: dma_intr: status=0x51 { DriveReady SeekComplete Error } hde: dma_intr: error=0x84 { DriveStatusError BadCRC } hde: dma_intr: status=0x51 { DriveReady SeekComplete Error } hde: dma_intr: error=0x84 { DriveStatusError BadCRC } hde: dma_intr: status=0x51 { DriveReady SeekComplete Error } hde: dma_intr: error=0x84 { DriveStatusError BadCRC } hdf: DMA disabled ide2: reset: success hdg: dma_intr: status=0x51 { DriveReady SeekComplete Error } hdg: dma_intr: error=0x84 { DriveStatusError BadCRC } hdg: dma_timer_expiry: dma status == 0x20 hdg: timeout waiting for DMA
and so on. First I used round IDE-Cables, 80c Ribbon, now I use flat 80c Ribbon. I tried with an CMD680-IDE-offboad-Controller and the onboard Promise PDC20276. Both show the same effect. The onboard-VIA VT 8233 (used for hda) never shows this error.

IRQ 16 is the CMD680, ide0 and ide1 is the onboard VIA VT8235. The machine acts as a fileserver, so it's worse falling back to PIO instead of DMA. The Mainboard is an MSI-Tech KT3 Ultra 2 with an VIA KT 333 Chipset (Athlon 1800 XP). For testing purposes I tried the CMD680 in an Intel P4-based Computer (same cables) but none of these nasty errors! The P4 was running a 2.4.23 and the Athlon a 2.4.23.
Used harddrives:

Any ideas, what I can change to get rid of these errors?
