Hallo, mein Laptop macht unregelmäßig die Grätsche, besonders nach einem WakeUp. Ich habe allerdings keine wirkliche Idee wo ich hier beim Troubleshooting ansetzen soll. Es gibt keine wirklichen Regelmäßigkeiten. Oft funktioniert der Wake Up. Manchmal crasht die Kiste aber auch im laufenden Betrieb. Vielleicht hat hier jemand einen guten Tipp. Die Fehler in /car/log/kernel.log sehen folgendermaßen oder ähnlich aus: Nov 25 00:44:19 lenz kernel: [ 1122.082036] PM: resume of drv:thermal dev:LNXTHERM:00 complete after 2032.010 msecs Nov 25 00:44:19 lenz kernel: [ 1122.109122] PM: resume of devices complete after 6285.409 msecs Nov 25 00:44:19 lenz kernel: [ 1122.109464] PM: resume devices took 6.284 seconds Nov 25 00:44:19 lenz kernel: [ 1122.109498] PM: Finishing wakeup.
