Hi everyone, I just experienced the freeze firsthand on my bench while testing the latest update. The system went into suspension and completely failed to wake up, forcing me to hard-reboot.
I managed to extract the kernel logs from that previous session using journalctl -b -1 -k and I'm attaching them here (log_crash_tonga.txt). As you can see, the kernel registers the wake-up triggers and even completes the suspend exit process (PM: suspend exit), but the display driver fails silently immediately after, cutting off any further video output or logging capability. This is running on an AMD Tonga/Polaris setup with Kernel 6.8.0-117-generic. Hopefully, this clean capture from the exact moment of the failure can help the maintainers pin down what is breaking the display pipeline during the resume phase.
