My system boots up fine using all previous (stable) fedora 12 kernels, I'm now running 2.6.31.12-174.2.3.fc12.i686.PAE When I try booting the newer 2.6.31.12-174.2.19.fc12.i686.PAE the boot starts, I get the usual prompt to enter the password for my encrypted raid1 device containing the /home filesystem, then it proceeds. But then it complains it's having trouble with the not-encrypted-raid-1-device that contains the / filesystem. (I have yet another not-encrypted-raid-1-device that contains /boot). I didn't make a picture yet, didn't write it down yet, but I believe the reported error is: "unable to access (or mount) /dev/md3 because of unsupport optional features (240)"
could this be caused by changes in dracut? I remember I couldn't boot when using dracut 003 and I had to revert. Now I have dracut 004-4 installed.
fstab contains: UUID=xxxxxxxxxxxxxxx / ext4 defaults,noatime 1 1
