Help with SATA drive/controller error [2nd try]

[Jerry Quinn <jlquinn@optonline.net>]

Hi, all.

I have a SATA drive and PCI controller I'm trying to get working without 
success.  This is a debian testing system on an AMD Athlon XP with a KT400 
chipset, with linux-image 2.6.14-2-k7 (Debian 2.6.14-4) running.

In the dmesg log, I get the following:

libata version 1.12 loaded.
sata_sil version 0.9
ACPI: PCI Interrupt 0000:00:0a.0[A] -> GSI 18 (level, low) -> IRQ 177
ata1: SATA max UDMA/100 cmd 0xF88D0080 ctl 0xF88D008A bmdma 0xF88D0000 irq 177
ata2: SATA max UDMA/100 cmd 0xF88D00C0 ctl 0xF88D00CA bmdma 0xF88D0008 irq 177

ata1: PIO error, drv_stat 0x51
scsi0 : sata_sil
ata2: no device found (phy stat 00000000)
scsi1 : sata_sil


I've search a bunch without success to figure out what this error means. 
Looking through kernel code seems to tell me that the drv_stat code is a 
combination of DriveReady, SeekComplete, and Error, but that doesn't leave me 
any better informed than before.

I'm not currently suspecting a kernel bug, but there doesn't seem to be enough 
documentation to have a clue as to what's going on.

The relevant part of lspci for the SATA controller gives:
