Installed F9Alpha with ext4 on root under lvm, booted fine and things were working until I updated Sunday 3/9. Dell Inspiron 6000 also had to use nolapic nohz=off to boot the installer. With kernel-2.6.25-0.105.rc5.fc9 (why is there an fc still :) ) After it reads LVM EXT4-fs: dm-1: not marked OK to use with test code. mount: error mounting /dev/root on /sysroot as ext4dev: Invalid arguement setuproot: moving /dev failed: No such file or directory setuproot: error mounting /proc: Nos such file or dierctory setuproot: error mounting /sys: No such file or directory Mount failed for selinuxfs on /selinux: No such file or directory (enforcing=0) <- booted up with (selinux=0) same thing switchroot: mount failed: No such file or directory Booting has failed. Default alpha kernel 2.6.24-2.fc9 I get: Starting udev: udevd-event[1270]: node_symlink: device node '/dev/rtc' already exists, link to '/dev/rtc0' will not overwrite it Just sits there. I was going to try 'rescue mode' from the install dvd and mount my system, but apparently that isn't setup for ext4 either.. :( I think I'm looking at a dead duck, but if anyone has a suggestion, let me have it. Not sure if Eric Sandeen is on this list or not.
