Hi,
This problem is not related to a specific kernel (it exists as well on 2.2.14
and on 2.3.39).
Motherboard data :
==================
Here are parts of my motherbord manual :
Motherboard name is VIB804DS from "PC PARTNER LIMITED".
Chip Set
--------
- VIA« APOLLO VPX.
BIOS
----
- 1MB Flash EPROM (Support PnP, APM, ATAPI & Windows« 95).
- IDE AUTO LBA Mode Supports HDDs up to 8.4GB.
- Anti-Virus Protection.
On Board I/O
------------
- Support two PCI Enhanced IDEs PIO Mode 3, Mode 4 and "Ultra DMA 33" Mode HDDs
My configuration :
==================
<*> Include IDE/ATA-2 DISK support
[*] Use multi-mode by default
...
[*] Generic PCI IDE chipset support
[*] Generic PCI bus-master DMA support
[*] Use PCI DMA by default when available
...
[*] VIA82CXXX chipset support (EXPERIMENTAL)
"cat /proc/pci" reports :
=========================
PCI devices found:
Bus 0, device 0, function 0:
Host bridge: VIA Technologies, Inc. VT82C585VP [Apollo VP1/VPX] (rev 35).

39).
Bus 0, device 7, function 1:

I/O at 0x6000 [0x600f].
Bus 0, device 13, function 0:

IRQ 11.
Non-prefetchable 32 bit memory at 0x10000000 [0x13ffffff].
-----------------------------
Now, *THE* problem : when try to enable DMA on every channel, I get the
following :
-----------------------------
[root@f5ibh] ~ # hdparm -d1 /dev/hda
[root@f5ibh] ~ # hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: DMA disabled
[root@f5ibh] ~ # ide0: reset: success
.. or even worse : I get sometime the system frozen with the disk activity led
on.
I get that on both disk : the first one is a Maxtor 90871U2, 8.4Gb, the second
is a ST3491A, 400Mb.
At boot time, the kernel reports the following :
================================================
Uniform Multi-Platform E-IDE driver Revision: 6.21
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: not 100% native mode: will probe irqs later

hdc: ST3491A, 408MB w/120kB Cache, CHS=899/15/62
I was, some time ago, running the 400Mb disk on an Intel card with a Triton
chipset, using the following kernel option :
[*] Intel PIIXn chipsets support
And the disk was running fine on the Inter Motherboard. So, I suppose the
problem is related to the chipset and the driver used.
I can survive without DMA enabled on the disk. But I'd like to have it
running. Is the problem related to the chipset ? Does the VIA driver support
(U)DMA as it is "EXPERIMENTAL" ?
Thank you for having a look to my problem.

Thank you for the patch. multi-io works fine now.
As you sign : 'IDE guy', I would ask you for a DMA problem. I'm sure _the_ IDE
guy can help me ;-)
