For an unknown reason, my RPi4 (latest version of Raspbian) stopped last night during an unattended-upgrade. The most recent traces I found in /var/log are (sorry, in French):

And other ones at 06:48, all related to the upgrade. So no obvious issue...
Unfortunately, when I try to restart the Pi, I get:
kernel panic - not syncing: Attempted to kill init! exitcode=0x00000007
I am unable to see the "real" message before this one as it scrolls very fast and I can't find any log.
My configuration is to boot on a hard disk (configured in cmdline.txt) so I changed it back to boot on the SD Card and there, everyting is working fine ==> the SD Card itself has no problem...
In this configuration, the hard disk is mounted automatically on /media/pi/ROOT, I can read it without any problem, and I checked it with fsck.ext4 and was told it is clean.
$ sudo fsck.ext4 -y /dev/sda1
e2fsck 1.44.5 (15-Dec-2018)
ROOT: clean, 418057/1835008 files, 3114608/7325696 blocks
So I'm a bit stuck...
