Found the following but my french isn't so good these days it seems.

So, I'm getting the following when trying to boot Mageia:
dracut warning:
cancelling resume operation. Device not found.
dracut warning: could not boot.
/dev/disk/by-vvid/297a9cba-cdc8-45fb-644f-f34681ez1cf1 does not exist.
dracut warning: /dev/resume does not exist
generating "/run/initramfs/rdsosreport.txt
dropping to debug shell
dracut:/#
Please be curteous when offering help. I'm really getting sick of the rudness that is typical of Linux forums.
