Red Hat Bugzilla – Bug 78365
Cdrom not present after compililng newest kernel
Last modified: 2008-08-01 12:22:53 EDT
Description of Problem:
If I install the newest kernel for RH 8.0 using up2date and reboot the OS, it is
not possible to use the cdrom in my ThinkPad T20.
If I boot with the original kernel of version 8.0 there is no problem.
Adding a line for cdrom to /etc/fstab does not help
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. update the RH8.0 to the latest kernel using up2date
2. reboot using the new kernel
cdrom is not a valid device
cdrom should be available for use
Dual boot on ThinkPad T20
The cdrom is in the dock's Ultrabay
I reported this problem more than two weeks ago.
Do you have any advice for me yet?
does it help if you type depmod -ae as root first?
I booted with the new kernel issued the command you reccomend and try to mount:
no success. Then I rebooted and tried to mount -> no success again :(
Do you have any other advice, please?
can you attach the output of the dmesg command in the failing kernel ?
Created attachment 87804 [details]
reuired dump of dmesg command
hmmmm your cdrom really appears to not be there for some reason
Yes: I know. But what to do?
If I boot with the 'old' kernel everything is fine : I can use the cdrom and I
have the corresponding line in /etc/fstab
If I reboot with the new kernel the line in/etc/fstab is gone and I cannot use
the cdrom. Adding a line to /etc/fstab now does not help.
Is the support for cdrom compiled in the newest kernel?
Other two weeks passed without any reply :o
I updated to the newest kernel but with the same negative results :(
Could you please check the cdrom support in the newest kernel?
