>Description:
I have a Gigabyte GA8I945P-G motherboard which has a ICH7 with chipid 0x27c08086.
On startup the system reports:
atapci1: <Intel ICH7 SATA300 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xf000-0xf00f at device 31.2 on pci0
atapci1: failed to enable memory mapping!
ata0: <ATA channel 0> on atapci1
ata1: <ATA channel 1> on atapci1
>How-To-Repeat:
Reboot.
>Fix:
In dev/ata-ata-chipset.c function ata_intel_ident() the ids array has an entry for chipid ATA_I82801GB_S1 (0x27c08086) with AHCI . The current Intel I/O Controller Hub 7 (ICH7) Family Specification Update (file 30701409.pdf) says (page 16) the device with ID 27c0h is "Desktop Non-AHCI and Non-RAID Mode".
I changed the ids array so the line for the ATA_I82801GB_S1 read:
{ ATA_I82801GB_S1, 0, 0, 0x00, ATA_SA300, "ICH7" },
rebuilt the kernel, rebooted and the "failed to enable memory mapping" message no longer appeared.
