------- Comment #42 from [EMAIL PROTECTED]  2007-12-12 11:33 -------
OK, I tested with vanilla 2.6.24-rc4 and the dbg4 patch

relevant parts of the vanilla 2.6.24-rc4 dmesg:
ata9: PATA max UDMA/133 cmd 0x1f0 ctl 0x3f6 bmdma 0xffa0 irq 14
ata10: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xffa8 irq 15
ACPI Exception (exoparg2-0442): AE_AML_PACKAGE_LIMIT, Index (0FFFFFFFF) is
beyond end of object [20070126]
ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.GTM_]
(Node ffff81007ff188c0), AE_AML_PACKAGE_LIMIT
ACPI Error (psparse-0537): Method parse/execution failed
[\_SB_.PCI0.IDE0.CHN0._GTM] (Node ffff81007ff18660), AE_AML_PACKAGE_LIMIT
ata9: ACPI get timing mode failed (AE 0x300d)
ata9.01: ATA-7: Maxtor 6L250R0, BAH41G10, max UDMA/133
ata9.01: 490234752 sectors, multi 16: LBA48
ata9.01: limited to UDMA/33 due to 40-wire cable
ata9.01: configured for UDMA/33
ata10: port disabled. ignoring.

with dbg4 applied the following lines are added to the dmesg:
+ata3: XXX skipping _GTM on empty channel
+ata4: XXX skipping _GTM on empty channel
+ata5: XXX skipping _GTM on empty channel
+ata6: XXX skipping _GTM on empty channel
+ata7: XXX skipping _GTM on empty channel
+ata8: XXX skipping _GTM on empty channel
+ata9: XXX skipping _GTM on empty channel
+ata10: XXX skipping _GTM on empty channel
The above ACPI error messages disappear, the detection is still identical.
Even if the XXX message claims that ata9 is empty the drive is still getting
detected correctly...

Looking at the patch I think it is missing the addition of the ATA_FLAG_XXX to
pata_amd, as I do not use pata_via.
But even with this flag added to all ata_port_info's I got no further output.
