Public bug reported:
Matériel :
- Lenovo Yoga Slim 7 14Q8X9
- Machine type : 83ED
- SoC : Qualcomm Snapdragon X Elite (X1E80100)
- BIOS : NHCN57WW, 03/01/2025
Système :
- Ubuntu 26.04 arm64
- Noyau : 7.0.0-29-generic
Problème :
La mise en veille démarre correctement, mais l’ordinateur se réveille
automatiquement après 4 à 12 secondes. Le ventilateur repart et la session
réapparaît.
Tests effectués :
- Veille profonde (« deep ») puis s2idle : même problème.
- Désactivation des sources de réveil capot, bouton Power, USB, contrôleurs
Qualcomm et MHI : même problème.
- Les seules sources restantes étaient clavier/touchpad I²C, mais leurs
compteurs de réveil sont à zéro.
- L’hibernation n’est pas supportée par le noyau actuel.
- fwupdmgr ne propose aucune mise à jour de firmware.
Journaux :
systemd-sleep indique « Performing sleep operation 'suspend' », puis « System
returned from sleep operation » quelques secondes plus tard, sans cause de
réveil identifiable.
Autre erreur au démarrage :
qcom_q6v5_pas 32300000.remoteproc: Direct firmware load for
qcom/x1e80100/LENOVO/83ED/cdsp_dtbs.elf failed with error -2
Résultat attendu :
La machine doit rester en veille jusqu’à une action utilisateur.
Résultat obtenu :
Réveil automatique quasi immédiat, rendant la veille inutilisable.
