Public bug reported: Power off/reboot hang on a Lenovo ThinkPad T495s kernel with 4.18 kernel.
I installed Ubuntu 18.04.2 on a Lenovo ThinkPad T495s, with kernel 4.18.0-15. After installation, the system will hang after power off/reboot. And I change the "Memory Card Slot" to Disabled in BIOS, the power off/reboot will be OK with 4.18 kernel. And then I changed the BIOS setting back to "Enable", then updated to 5.0.0-23 kernel, this issue will be fixed. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete -- 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/1843401 Title: Power off/reboot hang on a Lenovo ThinkPad T495s kernel with 4.18 kernel.
