Red Hat Bugzilla – Bug 116895
mod_probe -- ide-cd. error
Last modified: 2007-11-30 17:10:37 EST
Description of problem:
I cannot use the cdrom, and I'm not entirely sure why. I'll describe
the symptoms and what I've tried.
First off, it does not automount.
Secondly, I cannot do "mount" e.g.
$ mount /mnt/cdrom
ount: /dev/cdrom is not a valid block device
$ grep cdrom /etc/fstab
/dev/cdrom /mnt/cdrom udf,iso9660
noauto,owner,kudzu,ro 0 0
Thirdly, I see the following output from dmesg:
request_module: failed /sbin/modprobe -- ide-cd. error = 256
In case it's relevant, here is info on the kernel:
[root@kelley-home kelley]# grep kernel /boot/grub/menu.lst
# all kernel and initrd paths are relative to /boot/, eg.
# kernel /vmlinuz-version ro root=/dev/hda3
kernel /vmlinuz-2.6.1-1.65 ro root=LABEL=/ hdc=ide-scsi
(end of problem-description content)
Version-Release number of selected component (if applicable):
I don't know, really, what component is problematic. I'm running
Fedora Core 2 test 1.
Steps to Reproduce:
1. boot up
2. try above-named steps
Cannot use cdrom
Can use cdrom
I looked around for other advice on this, but couldn't find any, so I
thought it would be Ok to report it here, even though I wasn't sure
under which component to file the bug (the "cdr" as the component was
just the closest I could find, since the system demands a guess).
I do not think that the ide-scsi entry is needed anymore since scsi
emulation has been depracated with the 2.6.x kernels. I solved this
problem by simply eliminating the hdc=ide-scsi entry in grub.conf. I
think that the problem with this is that whatever program is writing
to the grub.conf file when installing a new kernel, allows the new
kernel to inherit the previous kernel's switches. However, in this
case the switch is no longer useful and causes problems.
Remove the hdc=ide-scsi, yes.
