dma_intr: status=0x51 { DriveReady SeekComplete Error }

Hello,

During starting my PC (Red Hat6.1, kernel 2.2.14), I get the following:
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x84 { DriveStatusError BadCRC }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x84 { DriveStatusError BadCRC }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x84 { DriveStatusError BadCRC }
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x84 { DriveStatusError BadCRC }
hdc: DMA disabled      

The disc is a:
hdc: Maxtor 91728D8, 16479MB w/512kB Cache, CHS=33483/16/63, UDMA

Is this a hardware problem, BIOS setting, ...

Thanks for your help.

Maybe both. Is this a UDMA66 capable drive? The BadCRC might be
something like a cable too long, or bad cable. More than likely it is an
incompatibility with the kernel drivers and drive mode. You might play
with DMA settings in the BIOS. But, probably worth trying Andre Hedricks
ide patch. Check kernel mirrors under people/hedrick.

I don't recall the exact errors I had, but if this is not it, it was
very similar on a ATA66 WD anytime I tried 'hdparm -d1'. The above
patch, and trying different kernel configs finally got it going. In my
case it ran fine if I didn't try to force it into DMA, but was dog slow.
