https://bugzilla.suse.com/show_bug.cgi?id=1179226 Bug ID: 1179226 Summary: System hang related to power saving Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: jc@phocean.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- # Issue : Screen and input devices would stop responding (black screen, no TTY), as soon as the computer goes into some low power mode. It can be triggered by locking the screen in Gnome (through gdm), and can also be reproduced in XFCE / LightDM by just leaving the computer for a while. # Impact : - black screen, no TTY access - unresponsive system (impossible to launch new processes, reboot, no way to switch init3 & init 5, etc.) - SSH/network access still available, existing process seem to run Moreover, no related log entry, no error (journalctl, dmesg...). # Notes : Hardware is very likely to be fine : - no issue with a Fedora LiveUSB ; - memtest tests passed. # Hardware : Asus PN40 Intel(R) Celeron(R) J4005 CPU @ 2.00GHz Intel Corporation UHD Graphics 605 (rev 03) # System Tumbleweed 20201123 I have no idea on how to debug it further. My huntch is that it is power saving related with Intel chipset. -- You are receiving this mail because: You are the assignee for the bug.
