Hi all, I've just downloaded and installed Fedora 3 x86_64 on an nforce 3 board with an Athlon 64 socket 939 and a SATA disk (important detail) As far as I could tell installation went well but upon reboot I got the fatal message when selecting fedora at the grub prompt : [...] ata2 failed to respond (30 secs) mkrootdev: label /1 not found mount: error 2 mounting ext3 mount: error 2 mounting none switchroot: mount failed: 22 umount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init! And that's it... I can boot in rescue mode ("linux rescue" at boot prompt ) and mount the file system in rescue mode. With Fedora 2 and the latest kernels (2.6.8) I had somewhat similar problems (same architecture exactly). With Fedora 2, I got the following message at boot : Kernel Panic : VFS Unable to mount root fs on unknown-block (0, 0) To be precise, my system worked fine with Fedora 2 and kernel 2.6.5-1.358 (and yes options in grub.conf were the same in fedora 2). Thus, my main questions are to the fedora list : what can I do (through kernel recompile, or grub.conf options)or whatever) to adress the issue ? Any suggestion is welcome... Alexandre
