 Posted: Tue Jul 13, 2004 1:23 am Post subject: can't find my CDROM-- udev problem or missing kernel module? |
 |
|
i'm having problems using my CD drive and i don't know if its a UDEV problem or if i'm missing some module.
i'm using the SCSI SATA driver (libata) built into the kernel and i'm loading the IDE driver as a module. quote from another post:
| Quote: | | What I did was to compile the PATA driver as a module, so that the SATA (libata) driver is used for my harddisk. The PATA driver loads later and only controls my IDE CD-ROM. |

when i look for /dev/ide it's not there. so maybe me loading the module after udev has done it's thing isn't letting it create the device nodes for the ide stuff.
i don't know enough about udev and writing "rules" ?? n stuff to say.... |

| Try putting ide-cd module into /etc/modules.autoload.d/kernel-2.6 that's what I had to do to get my ide-cdrom to work with udev |

THC,
got that in there:
| Code: | ppk@sledgehammer ppk $ cat /etc/modules.autoload.d/kernel-2.6
# /etc/modules.autoload.d/kernel-2.6: kernel modules to load when system boots.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/modules.autoload.d/kernel-2.6,v 1.1 2003/07/16 18:13:45 azarah Exp $
#
# Note that this file is for 2.6 kernels.
#
# Add the names of modules that you'd like to load when the system
# starts into this file, one per line. Comments begin with # and
# are ignored. Read man modules.autoload for additional details.
# For example:
# 3c59x

i see it come up in the list on boot up, but its after the udev message appears... so maybe it's too late? |

What version of udev are you using..since i got no problem with my cdrom and other stuff..i tried also as module as you but it appears in /dev/hdc and hdd ...so no problems..or you make a node (blockdevice) this also helps if there are problems..like nvidia was..

danone,
i'm running 027 it says:
| Code: | * sys-fs/udev
Latest version available: 025-r1
Latest version installed: 027
Size of downloaded files: 361 kB

| Quote: | | or you make a node (blockdevice) |
yea, i thought about that--i might have to make a node like i had to do with my nvidia card-- i followed Decibel's udev guide and it worked like a champ for the nvidia, but at this point i'm not exactly sure what the problem is: do i need some more modules loaded? is it just a udev problem? something else?
how can i find out for certain? |

Anyway, post the relevant part from your dmesg and also check do you get cdrom's in /dev/cdroms/
Also, how about adding to your bootloader (lilo/grub) configuration the devices, something like:
or whatever the device name is that's your cdrom. |

that's all that looks relevant in the dmesg output.... |
