Title: [Lenovo W520] Linux Freezing Issue At Boot Status in linux package in Ubuntu: Confirmed Bug description: Boot error occurs in a 64-bit system and only when certain conditions are met: BIOS/UEFI Settings: Config -> Display -> Graphics Device [Discrete Graphics] -> OS Detection for NVIDIA Optimus [Disabled] Security -> Virtualization -> Intel(R) Virtualization Technology [Enabled] -> Intel(R) VT-d Feature [Enabled] System hangs at boot time either after kernel log shows: [ 1.043982] ACPI: Video Device [VID1] (multi-head: yes rom: yes post: no) [ 1.047138] FUJITSU Extended Socket Network Device Driver - version 1.0 - Copyright (c) 2015 FUJITSU LIMITED or later after: [OK] Started Load/Save Screen Backlight Brightness of backlight:nv_backlight. The error occurs randomly (about 50% of all boot tries). The error has already been known for a long time (e.g. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/776999) and has never been fixed. It also occurs for older BIOS/UEFI versions and Ubuntu versions (e.g. 14.04) than shown in the report.

Another possible workaround (at least for the first hanging position is to use kernel parameters 'acpi_osi=! acpi_osi="!Windows 2009"' instead.
