Subject: Re: [HARDLOCK] 2.2.17 locks up hard on Ultra66/PDC20262 in DMA mode
 when using ide + raid-A0 + eepro100 patches

UPDATE:

Even with hdparm -d0 /dev/hde (to disable the DMA), I'm still getting:

hde: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hde: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=15347359,
sector=15347328
hde: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hde: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=15347359,
sector=15347328
hde: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hde: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=15347359,
sector=15347328
hde: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hde: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=15347359,
sector=15347328

But now I don't get the 
hde: DMA disabled 
error message anymore.  But it still locks really hard.  Also, I noticed
that you can't disable the "Use DMA by default" option in the kernel
without losing the "Promise PDC202xx" driver option.  So how do I disable
DMA in the kernel for this promise card (and the pii4x mb as
well)?  Because it doesn't seem like hdparm -d0 is helping.

Any other ideas guys?
