dma_intr: error=0x84 (common error, but pls read)


My P3-500 dual boot box boots up with certain dma_intr errors in /var/log/messages. Usually within 10 minutes or so, the machine will freeze completely and I will not be able to do a proper shutdown. I have found similar reports that hint towards hard drive transfer rate issues. I have tried other dma modes, and I even tried disabling dma with hdparm, but a freeze still occured after a few minutes. This is a dual boot system that exhibits no problems in Win98, though I have read that Windows is more leniant with poor hardware configurations. I have yet to try new cables and opening the case and untwisting the cable has not helped things. I am writing because if it really is a transfer rate issue, as most other posting of this problem seem to say, then why does the box still freeze after I disabled dma (disabling brought transfers down to 3 MB/s)? Also, if the drive is junk, then why has it been working fine with Win98 for 2+ years (I just installed Mandrake last month). I am also confused as to why my hdparm output (way below) does not have an asterisk on any dma mode unless I explicitly set one, then hdparm it again. This is my first post, I have tried to pack as much info as possible. Any help is appreciated!!!

The box: P3-500 (Katmai) on an ABIT WB6 motherboard (Intel 810E chipset) running Mandrake 9.0 and Windows 98. The /hda is a Western Digital Caviar 84AA 8.4G. Both the motherboard and the hard disk claim to support Ultra DMA 66.

The following /var/log/messages excerpt shows the 'dma_intr' errors:
The excerpt after this error excerpt is from 'hdparm -i -v /dev/hda':
