You confuse "boot previous kernel" with "boot from snapshot".
I think that, if I boot from a snapshot that had a different (previous) kernel version, then I am booting a previous kernel, yes? ;)
I suggested to boot a previous kernel, not an entire previous operating system, which is what booting a snapshot amounts to; to change fewest practical potential failure points at a time, not many. Booting a snapshot facilitates getting back in business quickly well, but not so much isolating or solving a problem arising from updating. But what is there in anything Marc has posted so far that suggests simply recreating the initramfs file will solve the problem? If the kernel update somehow did not complete properly, then I doubt dracut/mkinitrd will resolve the issue. Assuming that Marc cannot simply do a system rollback, would it make sense to a) boot into the previous kernel b) do an unconditional update on the following packages: kernel-default kernel-default-extra kernel-default-optional c) reboot ?
