Re: Missing Hardware After Update



Initial Message:

     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.



Alan Cox Suggestion:


     First thing - boot the old kernel (hit a key during grub and select the
     old one it kept) and make sure it still appears there, then boot the new
     kernel again so you are sure it is reproducible and depends on the kernel
     which I suspect will be the case.

     
Results:

     During the boot (I've got the inittab set to 3) I noticed that the message 'Starting udev' took much longer.
     After the reboot and log on as root, I entered:

         ls -ltr /dev/sr0
         brw-rw---- 1  root  disk  11,  0  2009-03-24  21:20  /dev/sr0
         mount /dev/sr0  /media/dvdrw
       --message stating that the media was mounted as read only--


I'm now back to my original question, How can I get /dev/sr0 back using my updated kernel?

TIA,
Gene
