CD-Device gone...
Hey guys,
i've got some problem with my cd-rom device. I think since changing to udev, which happend some time ago, my cd-rom devices disappeared.
There is no mor /dev/hdc or /dev/cd* or anythink anymore.
I think it might have to do something with udev or initramfs or maybe the kernel configuration, but it stopped working from one to antoher day and i got no idea why.
If you got an idea, please write, i miss my dvd device 
Bye

edit:
I just found that while browsing dmesg output, mybe this will help:
hdc: LITEON DVD-ROM LTD163, ATAPI CD/DVD-ROM drive
hdd: SAMSUNG CD-R/RW SW-408B, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15
hda: max request size: 128KiB
hda: 78165360 sectors (40020 MB) w/1024KiB Cache, CHS=65535/16/63, UDMA(66)
hda: cache flushes not supported
hda: hda1 hda2 hda3
hdb: max request size: 1024KiB
hdb: 160836480 sectors (82348 MB) w/1794KiB Cache, CHS=16383/255/63, UDMA(66)
hdb: cache flushes supported
hdb: hdb1
ide_cd: Unknown symbol blk_attempt_remerge
ide-floppy driver 0.99.newideI think the line "ide_cd: Unknown symbol blk_attempt_remerge" might be responsible for my missing devices

Re: CD-Device gone...
Well, if that's in your dmesg, I don't think it's the kernel's fault (it seems to detect both optical drives). I don't know much about udev though... Actually, I don't know much about the kernel either. Anyways, I'd look in the direction of udev. To be sure, you could perhaps check if they are present in /sys/block.

Nope, they are not

Re: CD-Device gone...
Aye, update your kernel, or if you use a custom one, use the patches in the announcements forum.

Re: CD-Device gone...
I don't know if it's related but I also had cdrom /dev disappeared after messing with mkinitrd. But it only affects boot procedure AFAIK.
