Hello Timo. I completed my testing using the generic_5.8.0 (2020-08-25 05:38) and generic_5.9.0 (current/2020-09-15 02:44) kernel files that you linked me.
The steps I used were as follows: 1. Download the kernel files (linux-image, linux-module) to a removable USB 2. Boot to target Ubuntu 20.04 environment using the EFI Ubuntu GRUB location 3. Copy the kernel files to the Ubuntu Desktop 4. Run "sudo dpkg -i" targeting the kernel files 5. Perform a warm reboot back into Ubuntu, followed by a device power off (Shutdown) 6. Repeat the test sequence used to show the failure, to determine if the new kernel files solves this issue a. Power on the device b. Boot to target Ubuntu 20.04 environment using the EFI Ubuntu GRUB location c. Perform a 'Restart' action in Ubuntu d. Allow the device to boot into Windows 10 (no Boot Menu selection was required, Win10 loads natively using Windows Boot Manager) e. Use the Start Menu to put the device to S3 Sleep Expected: The environment is able to enter the S3 Sleep state without issue using the new kernel files Actual: The environment experiences a WHEA_UNCORRECTABLE_ERROR BSOD event Did I perform this re-test correctly? If so, what are the next steps for this issue? Thank you. ** Attachment added: "Installing Linux Kernel Files" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1893820/+attachment/5411381/+files/wm_ubuntu_kernel_install.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893820 Title: DPLL2 override remains enabled after warm boot of Linux To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1893820/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
