Subject: [regression] CD-DA delay needed after insertion

We've found another regression in 2.6.25 w.r.t. CD media change on PS3.

It can easily be reproduced by:

  1. Inserting an audio CD
  2. Running 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.

It does not matter whether
http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fjejb%2Fscsi-rc-fixes-2.6.git;a=commitdiff_plain;h=d1daeabf0da5bfa1943272ce508e2ba785730bf0
is applied or not.

We haven't bisected it yet.

With kind regards,
