Hard drive errors in kernel output

[Cameron Matheson <cmatheson3@yahoo.com>]

Hey,

I enabled DMA in my kernel (w/ the VIA82xxxx support), and now it works (my
hard drive writes are about six times faster), but now I get weird errors in
the kernel output:

Partition check:
 hda:hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
 hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
 hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
 hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
 hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
 hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
 hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
 hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
 hdb: DMA disabled
 ide0: reset: success
  
Everything still works, so it's probably not a problem, but it is kind of
curious.  Here's my hdparm output if that matters:

/dev/hda1:
 multcount    = 16 (on)
 I/O support  =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 3739/255/63, sectors = 59568957, start = 63
	
Anyone know what these errors might mean (and what they do?)

Thanks,
Cameron Matheson
