Hi, ich kann das Notebook-Mikro nicht mehr benutzen und vermute, dass irgendwelche Kernelmodule nicht geladen werden. Mein Notebook ist ein Acer Travelmate P276. lspci: 00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 0b) 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) 00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b) 00:14.0 USB controller: Intel Corporation 8 Series USB xHCI HC (rev 04) 00:16.0 Communication controller: Intel Corporation 8 Series HECI #0 (rev 04) 00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 1 (rev e4) 00:1c.2 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 3 (rev e4) 00:1c.3 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 4 (rev e4) 00:1c.4 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 5 (rev e4) 00:1d.0 USB controller: Intel Corporation 8 Series USB EHCI #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation 8 Series LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 8 Series SATA Controller 1 [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation 8 Series SMBus Controller (rev 04) 01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 840M] (rev a2) 04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Kann mir jemand einen Tipp für die Fehlersuche geben? Grüße Thom
