           Summary: Dvd-burner not detected when ACPI=off, keeps probing
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.6.26
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Serial ATA
        AssignedTo: jgarzik at pobox.com
        ReportedBy: rob at bsdfreaks.nl


Latest working kernel version:
Earliest failing kernel version:
Distribution:Archlinux
Hardware Environment:
* Intel Core2Duo 2.4 ghz
* Foxconn P9657AA-8EKRS2H
(P965+ICH8R)
* Jmicron JB361

Problem Description: When I disable ACPI the DVD burner is not detected. It
keeps probing it.

I disabled ACPI since I still have stability problems with acpi enabled (see
bug report http://bugzilla.kernel.org/show_bug.cgi?id=10572)

I tried several kernels:
- Original Archlinux kernel 2.6.26
- 2.6.27-rc1-Zenmm1 with latest libata-dev from git

With all tested kernels the symptons are the same, when ACPI=off the dvd isn't
detected and it works direct when ACPI=on

I attach the output of the dmesg with and without acpi=on and lspci -vvv

Note: I'm on holiday from 28-8 till 19-9 so don't expect fast response.
