Hello Timo. Can you please document the steps on how to install these kernel files to the Live-USB versions of Ubuntu so that they are loaded at the time that the Live-USB is?
Or do these kernel files need to be deployed as part of a Windows/Ubuntu dual-boot system where both operating systems occupy the primary hard drive and make use of a multi-OS bootloader? If the latter is required, can you please provide documentation for how I can do this while maintaining the Windows OS as the primary OS for this bug testing? Thank you. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1893820 Title: DPLL2 override remains enabled after warm boot of Linux Status in linux package in Ubuntu: Incomplete Bug description: Ubuntu Version Target: 18.04.1 LTS (bootable Ubuntu USB stick) Package Version Target: Unknown Expected: Windows S3 Sleep actions with two DisplayPort monitors using Intel integrated graphics should be able to work without issue after entering a Windows OS from a previously loaded Ubuntu session Actual: Windows S3 Sleep actions with two DisplayPort monitors using Intel integrated graphics will result in a BSOD event if a Windows OS is loaded after an Ubuntu OS session that was ended by a warm reboot action Description: Using a dual-boot Ubuntu/Windows 10 desktop computer environment with two native DisplayPort MB connections to the Intel integrated graphics solution and two DisplayPort monitors it was observed that performing a Windows S3 Sleep action will cause a "WHEA uncorrectable error" BSOD event if the first OS loaded is Linux and the second OS Windows is loaded using a warm boot action. Investigating this BSOD event further it was determined that this issue is specific to the "Linux->warm boot->Windows->S3 Sleep" sequence as long as two DisplayPort monitors are connected to the desktop computer's DisplayPort MB connections. A deeper investigation of the cause of the BSOD identified that upon unloading Linux the DPLL2 override bit remains enabled and will cause a subsequent Windows desktop environment to be vulnerable to failure if it makes use of two DisplayPort-connected monitors. This issue can be reproduced using OEM hardware from either of Lenovo, HP, or Dell. This issue was first observed on the Q270/Q370 Intel chipset and the Intel 530/630 Graphics hardware. Calvin Hartwell of Canonical has been made aware of this issue and been provided issue details and video evidence.
