Re: DMA issue

Well, taking Justin's advice, I've pulled the disk put it into another computer and tried to use the smarttools on it. smartctl -a /dev/hdc shows it's SMART capable, however smart -s on fails. I'd take it this is a good sign the drives dead? 

But I just noticed that, when mounted ro it works okay.

Regularly. The drive will reset (with an audible click), then do a
little more and timeout again. I'm trying to install Sarge running
2.6.8, but the same problem happens with 2.4.26. I've tried booting
with noacpi, nodma, ide=nodma and noapic with no success. I've tried
different combos of connecting the drives, both on primary, dvd on
secondary, etc. I've disabled DMA in the BIOS, but it still seems to
try to use it. I've reset the BIOS. Is there anything else I can try?
Anyone else running one of these boards? Based on the dmesg output, it
doesn't seem like the noapic arg does anything on this board.

Are you sure the drive is good? I had problems like this, and smartmontools showed the drive was failing. I replaced it, and haven't had any problems 
since.
