I'm running Fedora 9 on a custom AMD Phenom Quad-Core with 8GB RAM installed, 2-SATA hard drives (Seagate 500GB and Seagate 1TB); HP DVD/CD RW Dual Layer with Lightscribe. Lo and behold, I've updated my running (this machine) from kernel 2.6.25-14 to kernel 2.6.27.19-78.2.30 (?) and have experienced the following: 1. My dual-layer DVD/RW and CD/RW drive has disappeared (it was /dev/sr0) The only messages I see that appear to be of concern are: [root@jpdsys3 log]# cat messages | grep -i reset | more Mar 22 14:46:30 jpdsys3 kernel: ata1: softreset failed (device not ready) Mar 22 14:46:30 jpdsys3 kernel: ata2: softreset failed (device not ready) Mar 22 14:53:55 jpdsys3 kernel: ata1: softreset failed (device not ready) Mar 22 14:53:55 jpdsys3 kernel: ata2: softreset failed (device not ready) All of the devices are SATA except the DVD drive. How can I get /dev/sr0 back? TIA, Gene
