I have a new ThinkPad T61 laptop running F8+updates. Most things are working just fine. I have a CDRW and DVD device on the notebook. Udev creates /dev/cdrom1 and /dev/cdrw1 devices but not /dev/dvd device, so when I try to use mplayer, xine etc to watch a dvd the device is known. As a temporary solution I used /dev/udev/devices directory and put in there a link from dvd--->sr0. This then creates the device and it works fine except I get an error message during boot to use makedev.d instead. When I add "dvd" into the file in that directory no device is created. Thanks, I am not sure what info is needed but here is some: ThinkPad BIOS 7LETB2WW (2.12 ), EC 7KHT24WW-1.08 Lenovo ThinkPad T61, model 7662CTO ======================messages==================================== kernel: ata4.00: ATAPI: HL-DT-STCD-RW/DVD DRIVE GCC-M10N, 1.02, max UDMA/33 kernel: udev: renamed network interface ath0 to wlan0 kernel: firewire_core: created device fw0: GUID 00016c00005a5b19, S400 kernel: ata4.00: configured for UDMA/33 kernel: scsi 3:0:0:0: CD-ROM HL-DT-ST RW/DVD GCC-M10N 1.02 PQ: 0 ANSI: 5 kernel: scsi 3:0:0:0: Attached scsi generic sg1 type 5 kernel: ACPI: PCI Interrupt 0000:00:1b.0[B] -> GSI 17 (level, low) -> IRQ 17 ======================================================================== ========================dmesg===================================== ata4.00: ATAPI: HL-DT-STCD-RW/DVD DRIVE GCC-M10N, 1.02, max UDMA/33 scsi 3:0:0:0: CD-ROM HL-DT-ST RW/DVD GCC-M10N 1.02 PQ: 0 ANSI: 5 scsi 3:0:0:0: Attached scsi generic sg1 type 5 ACPI: PCI Interrupt 0000:00:1b.0[B] -> GSI 17 (level, low) -> IRQ 17 hda_intel: probe_mask set to 0x1 for device 17aa:20ac PCI: Setting latency timer of device 0000:00:1b.0 to 64 Driver 'sr' needs updating - please use bus_type methods sr0: scsi3-mmc drive: 24x/24x writer cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.20 sr 3:0:0:0: Attached scsi CD-ROM sr0 =================================================================

Hi, There was no /sys/class/block/sr0/uevent but /sys/block/sr0/uevent so I used that. Messages from udevmonitor on console is below and I will attach the stuff from /var/log/messages. # udevmonitor udevmonitor will print the received events for: UDEV the event which udev sends out after rule processing UEVENT the kernel uevent UEVENT[1208989634.937943] add /block/sr0 (block) UDEV [1208989635.114812] add /block/sr0 (block)

Please attach: /etc/udev/rules.d/70-persistent-cd.rules and then remove it. This file should be regenerated. Hopefully after that you should have /dev/dvd
Created attachment 303709 [details] old persistent rules file Removing this file solved it. I disk duplicated from my desktop to my laptop over the network and this file came from the desktop version. Thanks.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
