Summary: ata_piix blocks ahci from accessing the harddisk
Product: Drivers
Version: 2.5
KernelVersion: 2.6.23-0.129.rc3.git4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: drivers_other at kernel-bugs.osdl.org
ReportedBy: romal at gmx.de
Most recent kernel where this bug did not occur: 2.6.17
Distribution: Fedora 6 Core test 3
Hardware Environment: Toshiba Tecra S3
Software Environment: Fedora & Ubunu
Problem Description:
If I boot Fedora 7 or Ubuntu 7 install dvd with kernel parameter noprobe, the
problem can be fixed.
When manually selecting the drivers, the driver ahci has to be loaded first,
that brings up the harddisk. Second the driver ata_piix has to be loaded, to
get
access to the optical drive.
Installed system does not boot.
Steps to reproduce:
lspci
00:00.0 0600: 8086:2590 (rev 03)
00:01.0 0604: 8086:2591 (rev 03)
00:1b.0 0403: 8086:2668 (rev 03)
00:1c.0 0604: 8086:2660 (rev 03)
00:1c.1 0604: 8086:2662 (rev 03)
00:1d.0 0c03: 8086:2658 (rev 03)
00:1d.1 0c03: 8086:2659 (rev 03)
00:1d.2 0c03: 8086:265a (rev 03)
00:1d.3 0c03: 8086:265b (rev 03)

00:1e.0 0604: 8086:2448 (rev d3)
00:1f.0 0601: 8086:2641 (rev 03)
00:1f.1 0101: 8086:266f (rev 03)
00:1f.2 0106: 8086:2653 (rev 03)
01:00.0 0300: 10de:0148 (rev a2)
02:00.0 0200: 11ab:4362 (rev 15)
05:05.0 0280: 8086:4220 (rev 05)
05:0b.0 0607: 104c:8031
05:0b.2 0c00: 104c:8032
05:0b.4 0805: 104c:8034
Thus bug is present in Ubuntu and Fedora, so I don`t think this is a
distribution-specific bug.
