Hi, Several users including me are experiencing an issue with Thinkpads becoming completely unresponsive after several hours. This seems to happen more often shortly after the system has been idle for some time. The issue only occurs when the Thinkpad is already connected to a USB C doc= king station before booting. dmesg shows regular "BUG: kernel NULL pointer dereference, address: 0000000000000000" that do not cause a crash however. These only show up, when the systemd upower.service is running. In the attached dmesg.txt, I booted with upower.service disabled and starte= d it manually which immediately lead to the NULL pointer dereference (but no cra= sh). We bisected and found the offending commit in https://bbs.archlinux.org/viewtopic.php?id=3D279027 Please see the attached bisect-log.txt . --=20 You may reply to this email to add a comment.
