** Description changed: Hi, Since I updated to kubuntu 16.10 I quite often have the situation that my laptop completely freezes after login in sddm (that means: while KDE is loading). During that time: - Fans run high - laptop is completely unuseable (no mouse or keyboard-input accepted, can't switch to other terminal, etc ...) - only a long press to the power-button helps . - network-connections break (tried to monitor the system remotely, but when the error occurs, also the ssh-connection fails) - the kern.log stops and contains only a few lines of rubbish: Dec 3 11:01:37 orbit kernel: [ 18.951805] ACPI: \_SB_.PCI0.PEG0.PEGP: failed to evaluate _DSM Dec 3 11:01:37 orbit kernel: [ 18.951808] ACPI Warning: \_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20160422/nsarguments-95) Dec 3 11:01:37 orbit kernel: [ 18.951891] nouveau 0000:01:00.0: DRM: suspending console...
