MoinOoozing linux and irregularly the power dropped or something strange happened and now the machine doesn't boot anymore?
Kernel panics cause rootfs cant be mounted? Start a linux system from some USB-Drive and try this, If LVM is involved start here:vgscan
vgchange -ay
lvs
mount /dev/mapper/nameoflvm-root-partiton /mnt
mount /dev/sda1 /mnt/bootWithout LVM start here
mount /dev/changeme.rootfilesystem /mnt
mount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt
update-initramfs -u
update-grub
