Bonjour,
Mon laptop LENOVO (acheté en début d'année 2020) tourne sous cette distribution ( Ubuntu 20.4 ) :
https://doc.ubuntu-fr.org/focal
Voici l'intégralité du fichier /var/log/dmesg :
http://ramix.org/rpm2020/dmesg111 (comporte 1122 lignes)
Ce laptop a toujours parfaitement fonctionné mais depuis une semaine il y a des plantages (plusieurs par jour) dont j'ignore la cause.
Merci de m'aider à trouver la cause.
Ce jour à 8H49 il y a eu un plantage et cet extrait de /var/log/syslog comporte une centaine de lignes (celles relatives au plantage):
http://ramix.org/rpm2020/syslog111
dont celles-ci ( avant le plantage) :
Oct 6 08:37:30 rpm2020 dbus-daemon[1279]: [session uid=1000 pid=1279] Activating service name='org.freedesktop.Notifications' requested by ':1.626' (uid=1000 pid=36497 comm="/usr/lib/thunderbird/thunderbird " label="unconfined") Oct 6 08:37:30 rpm2020 dbus-daemon[1279]: [session uid=1000 pid=1279] Successfully activated service 'org.freedesktop.Notifications' Oct 6 08:42:03 rpm2020 rtkit-daemon[1098]: Supervising 4 threads of 2 processes of 1 users.

et celles-ci ( après le plantage) :
