[Bug 2167012] [NEW] System performs hard reset shortly after boot with kernel 7.0.0-31-generic

Public bug reported: Environment Hardware: XMG Focus 17 M25, NVIDIA RTX 5070 Ti (full 140-150W variant) Kernel (broken): linux-image-7.0.0-31-generic Kernel (working): linux-image-7.0.0-30-generic GPU driver: nvidia-driver-580-open, version 580.173.02, DKMS-built cleanly for both kernel versions Desktop environments installed: GNOME, KDE Plasma, XFCE Symptom Machine reboots abruptly with no warning while running kernel 7.0.0-31 journalctl -b -1 ends without any clean shutdown/reboot log entries Occurred multiple times in short succession (boots lasting ~2-3 minutes each) shortly after a kernel/driver update occurred on a freshly booted, idle system (ruled out thermal throttling via sensors / kernel thermal zone logs, which showed nothing abnormal) Under GNOME (Wayland) and KDE Plasma, the system crashed Under XFCE (X11, minimal), the system ran stably on the same kernel Downgraded/pinned to linux-image-7.0.0-30-generic (apt-mark hold on linux-image-generic-hwe-26.04, linux-generic-hwe-26.04, linux-headers- generic-hwe-26.04). System has been stable since.
