pci ide controller

[Ron Dzierwa]

anybody have any experience with pci ide controllers under 5.2?  I have an
athlon system with a soyo dragon mb (via chipset).  i've been trying to use
a promise ata100 controller with a couple of wd3000bb drives and the ata
driver keeps hanging when i put the system under any load.  The test i was
doing was to simply read the raw disks with dd:

  dd if=/dev/ad4 of=/dev/null bs=1m

dmesg gets the following:
ad4: TIMEOUT - READ_DMA retrying (2 retries left) LBA=1477536
ad4: WARNING - READ_DMA interrupt was seen but timeout fired LBA=1477536
ad4: WARNING - READ_DMA interrupt was seen but taskqueue stalled LBA=1477536

the dd process goes into a STOP state (as indicated by top), and can't be
killed.    The controller/disks work well enough to do simple things, like
newfs, dump, restore, and fsck, but when i try to do a lot of i/o quickly,
it always hangs.   I want to use the disks as a stripe for a multimedia app,
so this simply won't do.

it looks like the driver doesn't even recognize the controller, so i really didn't
expect it to work all that well.   Before i went out tried to buy every pci ide
controller on the market just to find one that works, i figured i'd ask to see
if anybody has one that works well.

also, has anybody used the VIA 8237 SATA controller with 5.2?  I suppose
i could just junk the ide drives and use sata but i really don't want to go out
and buy a bunch of disks just to find out the sata controller doesn't work with
Soren's driver either.
