Hi,
I have a new Laptop, a Medion E4214, with a standard xubuntu LTS 14.04 installed. My problem is, that the notebook does neither reboot nor powerdown. It hangs late in the powerdown/reboot sequence, with no error message shown on the console, and I need to hold down the power button for 5s to switch it off hard.
I switched off the grub splash screen, to not miss any console messages, I stopped X, network, sound and bluetooth, so that the loaded modules are only (lsmod output):
Module Size Used by i915 1146880 1 drm_kms_helper 126976 1 i915 drm 352256 3 i915,drm_kms_helper i2c_algo_bit 16384 1 i915 video 28672 1 i915 ahci 36864 2 libahci 32768 1 ahci
The problem persists, so if it the problem is in one of the drivers, it must be one of the drivers above. I tried to start with the reboot= set to acpi, bios, force or pci, to no avail.
Needless to say, that the notebook reboots/powers off when running windows 8.1
The system is mostly intel, ValleyView SoC, with a Realtek Ethernet controller. Here is what lspci has to say:
00:00.0 Host bridge: Intel Corporation ValleyView SSA-CUnit (rev 0e) 00:02.0 VGA compatible controller: Intel Corporation ValleyView Gen7 (rev 0e) 00:12.0 SD Host controller: Intel Corporation ValleyView SDIO Controller (rev 0e) 00:13.0 SATA controller: Intel Corporation ValleyView 6-Port SATA AHCI Controller (rev 0e) 00:14.0 USB controller: Intel Corporation ValleyView USB xHCI Host Controller (rev 0e) 00:17.0 SD Host controller: Intel Corporation ValleyView MIPI-HSI Controller (rev 0e) 00:1a.0 Encryption controller: Intel Corporation ValleyView SEC (rev 0e) 00:1b.0 Audio device: Intel Corporation ValleyView High Definition Audio Controller (rev 0e) 00:1c.0 PCI bridge: Intel Corporation ValleyView PCI Express Root Port (rev 0e) 00:1c.1 PCI bridge: Intel Corporation ValleyView PCI Express Root Port (rev 0e) 00:1d.0 USB controller: Intel Corporation ValleyView USB Enhanced Host Controller (rev 0e) 00:1f.0 ISA bridge: Intel Corporation ValleyView Power Control Unit (rev 0e) 00:1f.3 SMBus: Intel Corporation ValleyView SMBus Controller (rev 0e) 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)
Are there any options for startig / compiling to debug that further? Any tips appreciated.
Nils
