[re-sending after being pointed to the right mailing list] Hi all, I was brave enough to upgrade my primary work laptop - a Lenovo laptop T440s - from Fedora 22 (workstation) to the Beta of version 23. The upgrade was smooth, Gnome 3 is working great, and it's all looking gorgeous but the machine occasionally seems to "freeze" and I have to long-press the power button to force a shut down as it won't react to any other key combination I tried (from ctrl-alt-del to ctrl-alt-F1..F9, ctrl-alt-backspace). Kernel version is 4.2.1-300.fc23.x86_64 (not tainted nor customized). The boot command line is the "vanilla" one: BOOT_IMAGE=/vmlinuz-4.2.1-300.fc23.x86_64 root=UUID=f12bc342-dcf1-4c72-815f-4d3c0475a9f0 ro rootflags=subvol=root vconsole.font=latarcyrheb-sun16 rhgb quiet Is there anything I can do to help getting this fixed? I guess a good start would be to report it on some issue tracker, but I'm not sure which one, or which component: I probably need some help to narrow it done somewhat?
