Among others I use a Radxa Rock Pi 4a with  nvme disk. 

The latest update to kernel 6.12.10 ended with a not bootable system. With the 
release kernel and the update kernel 6.8.10 everything worked flawlessly 


I get:

[ OK ] Reached target bsasic.target - Basic System.
rk3399-dmc-freq ffa80000.dmc: Invalid operating-points in device tree.
rk3399-dmc-freq ffa80000.dmc: probe with driver rk3399-dmc-freq failed with 
error -22
[ OK ] Stopped systemd-vconsole-setup.service - Virtual Console Setup.
. . .
[  ...... ] dracut-initqueue[557]:    Volume group "fedora" not foumd 
[  ...... ] dracut-initqueue[557]:    Cannot process volume group fedora


That cannot work, indeed, because the VG on this system was renamed due to LVM 
naming conflicts.

Additionally, the directory /etc/lvm/devices is empty, but it should contain a 
valid device file. 

I can mount the EFI and the boot partitions of the nvme disk and access all 
files therein. 


I would like to switch back to the previous kernel 6.8.10 and wondering how to 
do that in the dracut shell. If I remember correctly there is a tool available, 
but I don’t remember the details and my internet research didn't come up with 
anything useful.  


I would greatly appreciate any advice on how to revert to the previous kernel.


Thanks
Peter
