PROBLEM: 2.4.20 on ICH4 : ide-cdrom/ide-scsi problems reading cds

[David Glance]

Please cc me directly as I am not subscribed to the list.

I am getting problems (intermittent) trying to play audio CDs using 
2.4.20 with an ICH4 controller (although I don't know if the ICH4 is 
relevant) - the problem is intermittent and I can eventually play the CD 
by ejecting and loading the CD a couple of times. The problem below is 
with the ide-cdrom module but it is exacerbated when I use ide-scsi instead.

I have tried this with 2 different CD RW drives (I went and bought a new 
drive to check that the error was not with the old HP.
I also have applied the latest ACPI patch (to get this machine to power 
off correctly) - but I have tested without the patch and I still get the 
same problem.

Any help would be appreciated. Let me know if you need any further 
information.
