Title: Thinkpad T430 Power Cycles instead of rebooting Status in grub package in Ubuntu: Incomplete Bug description: After installing Xubuntu 20.04, Thinkpad T430 does not reboot properly any more. Expected behavior: Power LED and HDD stay on, System reboots. Actual behavior: System switches off (including power LED and HDD which leads to emergency head parking and loud click noise) and switches back on after 5 seconds. Problem occurs with Xubuntu 20.04 and Ubuntu 20.04 even when booted from live USB medium. It also occurs with Mainline Kernel 5.6.7 which I installed for testing. It does not occur with several live media used for testing (Xubuntu 18.04, Windows 10, Manjaro 20, MX 19) or when rebooted from within GRUB2 on my Xubuntu installation.
