Description Michael Fulbright 2003-02-25 18:42:06 UTC

The chipset on this Compaq machine is:

00:0f.1 IDE interface: ServerWorks CSB5 IDE Controller (rev 92)

In the boot kernel (2.4.20-4smp-BOOT) the proc entry /proc/sys/dev/cdrom/info
returns bogus information.  The system has a CD burner as /dev/hda and a DVD-ROM
drive as /dev/hdb.  In the normal kernel we get:

CD-ROM information, Id: cdrom.c 3.12 2000/10/18
 
drive name:             sr1     sr0
drive speed:            40      32
drive # of slots:       1       1
Can close tray:         1       1
Can open tray:          1       1
Can lock tray:          1       1
Can change speed:       1       1
Can select disk:        0       0
Can read multisession:  1       1
Can read MCN:           1       1
Reports media changed:  1       1
Can play audio:         1       1
Can write CD-R:         0       1
Can write CD-RW:        0       1
Can read DVD:           1       0
Can write DVD-R:        0       0
Can write DVD-RAM:      0       0

In the -BOOT kernel we kernel:

CD-ROM information, Id: cdrom.c 3.12 2000/10/18
 
drive name:             sr1     sr0
drive speed:            116     116
drive # of slots:       1       1
Can close tray:         1       1
Can open tray:          1       1
Can lock tray:          1       1
Can change speed:       1       1
Can select disk:        0       0
Can read multisession:  1       1
Can read MCN:           1       1
Reports media changed:  1       1
Can play audio:         1       1
Can write CD-R:         1       1
Can write CD-RW:        1       1
Can read DVD:           1       1
Can write DVD-R:        1       1
Can write DVD-RAM:      1       1

Not only are the speeds silly, but it indicates both can burn CD/DVDs. This
causes us to indicate both should use ide-scsi in the grub.conf, which is incorrect.

Is this specific to serverworks or does that drive combo fail with non serverworks ?

If you boot an installed box with init=/bin/sh then mount /proc by hand and
check the
info (you may need to modprobe the cd drivers obviously) is it also wrong ?

Comment 2 Jeremy Katz 2003-02-26 16:29:35 UTC

To add what I said on IRC yesterday evening here...

1) Boot UP kernel to init=/bin/bash, mount /proc, modprobe ide-cd --> everything
is fine
2) Boot BOTO kernel to init=/bin/bash, mount /proc, you get the bizarre
incorrect numbers

The main difference between the two afaik is that ide-cd is built-in to the BOOT
kernel as opposed to modular everywhere else.

Was this a DL360 ?

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
