IDE bugs for intel 440LX chipset in Test12?
All I can say right now is that enabling DMA on a 440LX chipset with 2.4.0-test12 or any other kernel I can remember has caused DMA timeout and ide-reset problems. Disabling dma on the harddrives doesn't help
that much either, I still get ide resets. What I'm looking for right
now is some information on how to log what the kernel recieves from the harddrive and possibly what it sends so I can give rik some better information on what's going on in this chipset. Thanks.

Anyone with a PIIX4,PIIX4AB,PIIX4EB has a hardware bug.
If many of the chipset makers followed and reverse engineered their stuff against that bug then ths explains all of the timeout issues.
I am working on a fix, but do not have one yet.
Cheers,
