Let me be more exact... 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. The DVD drive is on the single IDE connection and it is set to be the slave (factory default?) TIA, Gene
