Problems with IDE CF

[Joe Schmo]

Hi,
We recently encountered a problem very similar to an
old post in majordomo forum. We boot up a linux image
written on a RiData 128mb CF card on IDE interface
(hda), the kernel dumps these error messages on the
screen:

hda: CF-ATA, ATA Disk drive
ide: Assuming 33 MHz system bus speed for PIO modes,
override with idebus=xx
hda: set_drive_speed_status status=0x51 { DriveReady
SeekComplete Error }
hda: set_drive_speed_status error=0x04 { Drive Status
Error }
...
hda: dma_intr: status=0x51 { DriveReady SeekComplete
Error }
hda: dma_intr: error=0x04 { Drive Status Error }
...
hda: DMA disabled
...
hda: lost interrupt
hda: lost interrupt
hda: lost interrupt
[it keeps repeating the last message every few
seconds]

The same image has a very high failure rate when
installed in RiData CF card, but always work when
installed in another brand of CF.  It seems the
original post solved part of their problem after
receiving a recommended solution from Soewono, but I
can't find Soewono's original message from "Linux
Kernel Archive". 

This is very urgent since we will have a meeting with
customer today, and if we can't provide a solution we
won't win the deal. Could anyone please shed some
light? Thanks!

Soewono, 
Excellent, and thank you very much. That fixed the
ludicrous delay and such 
while coming up. I still get the kobject_register
error, however.
