           Summary: 2.6.25 regression: delay needed after audio CD insertion
           Product: SCSI Drivers
           Version: 2.5
     KernelVersion: 2.6.25
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
        AssignedTo: scsi_drivers-other@kernel-bugs.osdl.org
        ReportedBy: geert@linux-m68k.org


Latest working kernel version: 2.6.24
Hardware Environment: PS3
Problem Description: Audio CD cannot be read within 10 seconds after insertion

Steps to reproduce:
  1. Insert an audio CD
  2. Run the following command as soon as the blue CD/DVD/BD drive LED
     stops blinking and is lit continuously:

     cdparanoia -Z -q 1-1[:1] /dev/null || echo failed

On 2.6.25 (and current mainline), you have to wait ca. 10 seconds after
insertion, or it will fail.
On 2.6.24 and older, it just works immediately.

(I could reproduce it on an Athlon with sym53c8xx SCSI running a Debianized
 2.6.25 kernel, too, but I didn't try a 2.6.24 kernel there)

The problem was introduced by:
