I fixed it by generating new initrd using mkinitrd using /etc/fstab with ext3 for the volume... I wondered what was the problem, because the older kernels booted OK and mount was seeing the mounted partition as ext4, though at boot it seemed like if it was mounting it as ext3. Perhaps I'll give it one another try (I can afford to screw up one of the two kernel initrd images now, when I know, how to fix it...). Just to be precise - the kernels of which the initrd images were generated before the /etc/fstab change worked, the kernels with initrd images generated after the change failed on switch_root. But I clearly remember I used ext4 (not ext4dev) at first, so when I fixed the computer (and could boot again into rawhide) I tried changing it to ext4dev for one of the kernels and it didn't worked (switch_root error again). Maybe I made some typo in the fstab... Martin
