2.5.1-pre5 AudioCD with cdrom modules

2.5.1-pre5 AudioCD with cdrom modules

[Pierre Rousselet]

What may cause an AudioCD no being recocognized at first attempt but
only after unloading/reloading the modules ide-cd cdrom ?

I'm testing 2.5.1-pre5 + devfs-patch-v202.

My CRD-8240B is known as /dev/cdroms/cdrom0 in fstab, to mount it
manually on /cdrom, and in the gnome CD player gtcd preferences panel.

ide-cd and cdrom are loaded at boot time (i don't need that, 2.4.16 does
it as well). After loging in i can mount /cdrom but if it is an AudioCD
gtcd tells me 'no disc'.

After rmmod ide-cd cdrom, gtcd finds the AudioCD OK.

This doesn't happen on plain 2.4.16

Please try kernel 2.4.17-pre2 + devfs-patch-v199.2. That will help
determine if the problem is devfs-related, or (more likely) due to the
block I/O changes happening in 2.5.

Excellent, can you hear Diana Krall? 2.4.17-pre2 + devfs-patch-v199.2
does not have this feature. The AudioCD is identified at the first
attempt.

??? You'll have to explain what you mean by this.

OK, since 2.4.17-pre2 + devfs-patch-v199.2 works fine, it suggests the
block I/O changes in 2.5. I've Cc'ed Jens, who likes hearing about
these problems :-)
