https://bugzilla.suse.com/show_bug.cgi?id=1234860 Bug ID: 1234860 Summary: Regression: Lenovo T14s Gen 2 AMD crashes on resume from suspend on kernel 6.12 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: dheidler@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- The laptop comes up far enough from suspend to show the open applications on the desktop but the mouse doesn't react. The applications are NOT frozen - journalctl shows something (even though redirecting it into a file didn't show any content in that file after going into suspend. Then something really strange happens: - The display brightness goes through all the possible brightness steps - When reaching the full brightness it goes back to dark and starts over again - This process repeats faster and faster - Finally the screen goes completely dark -- You are receiving this mail because: You are the assignee for the bug.
