Subject: Promise PDC20262 in kernel 2.4.x
Sender: linux-kernel-owner@vger.kernel.org

Setup: Dell Dimension XPS T-700r
	Onboard PCI Controller:
		Primary IDE: empty
		Secondary IDE: CD, CD-RW
	Promise PDC 20262 IDE card
		Primary: Quantum Fireball 30Gb
		Secondary: Seagate ST330630A

Symptoms: No recent stock distribution install disk I have will boot. (RH 7.x,
MDK 8.x)  The boot sequence gets all the addresses right, but dies after
printing
	ide2 at 0x10f8-0x10ff,0x10f2 on irq 10
I haven't found kernel options that will cure this.  The addresses printed
by the kernel are all correct, and
	ide0=noautotune,ide2=noautotune
has no effect.  (This has all been reported before.  If someone can point
me to a FM to R, I would be eternally grateful :-)

BUT

I discovered by accident that a kernel with NO Promise support compiled
in boots just fine!  The resulting system is slow - I suspect it's not
using DMA - but the system does run.
This statement applies to kernels 2.4.5, 2.4.10 and 2.4.14.
(For anyone with a similar problem who might be reading this, the
implication is that a disk built on another machine with a custom
kernel will boot when installed.)

So... anyone have any insight?  I'm willing to change configuration,
test patches, provide more information, etc.

Gory details:

Kernel configuration that works (IDE stuff only):

CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_BLK_DEV_IDEFLOPPY=y
CONFIG_BLK_DEV_IDESCSI=y
CONFIG_BLK_DEV_CMD640=y
CONFIG_BLK_DEV_CMD640_ENHANCED=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_IDEPCI_SHARE_IRQ=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_BLK_DEV_ADMA=y
CONFIG_BLK_DEV_OFFBOARD=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_BLK_DEV_PIIX=y
# CONFIG_PIIX_TUNING is not set
# CONFIG_BLK_DEV_PDC202XX is not set
# CONFIG_PDC202XX_BURST is not set
# CONFIG_PDC202XX_FORCE is not set


Diffs with kernel configuration that doesn't work:

< # CONFIG_BLK_DEV_PDC202XX is not set
---
> CONFIG_BLK_DEV_PDC202XX=y


(Turning on CONFIG_PDC202XX_BURST made no difference.)

One final note: The RH 7.2 kernel (and maybe earlier ones, I can't remember)
puts the Promise controller at hde/f and hdg/h instead, but the net result
is the same.
