Public bug reported: System experiences repeated hard freezes (requires power button reset) under Wayland with GNOME Shell 50 on kernel 7.0.0-10-generic. Audio continues playing during freeze, indicating the kernel is still running but the display compositor is deadlocked.
== System Information == Ubuntu 26.04 (Resolute Raccoon, development branch) Kernel: 7.0.0-10-generic #10-Ubuntu SMP PREEMPT_DYNAMIC (7.0.0-rc4) GNOME Shell: 50.0 Session: Wayland CPU: AMD Ryzen 9 3900X 12-Core Processor GPU: NVIDIA GeForce RTX 2070 SUPER (PCI ID: 10de:1e84) NVIDIA Driver: 580.126.09 (tested both open and closed kernel modules) Motherboard: ASRock B550 Steel Legend (BIOS P3.40) RAM: 32GB (2/4 slots populated) == Symptoms == 1. Complete GUI freeze - mouse, keyboard, display all unresponsive 2. Audio continues playing (kernel still running) 3. No kernel panic/oops in logs 4. No NVIDIA Xid errors logged 5. Hard power reset required 6. Occurs approximately every 20-60 minutes under normal desktop use 7. Occurs with both nvidia-driver-580-open AND nvidia-driver-580 (closed) == Freeze Pattern (consistent across all occurrences) == The following sequence appears in journalctl before every freeze: 1. Optional: gnome-shell logs "Value 9223372036854775807 cannot be safely stored in a JS Number and may be rounded" (INT64_MAX, likely invalid Wayland presentation timestamp) 2. Kernel logs "NOHZ tick-stop error: local softirq work is pending, handler #200!!!" (and sometimes #08, #01, #80) 3. NOHZ errors increase in frequency 4. All logging stops - system frozen == Example logs from crash at 23:19 (Mar 31 2026) == Mar 31 23:19:58 kernel: NOHZ tick-stop error: local softirq work is pending, handler #200!!!

[no further log entries - system frozen] == Example logs from crash at 22:49 (earlier same day) == Mar 31 22:49:23 gnome-shell[16774]: Value 9223372036854775807 cannot be safely stored in a JS Number [repeated ~15 times] Mar 31 22:49:34 kernel: NOHZ tick-stop error: local softirq work is pending, handler #200!!! [system frozen shortly after] == Additional observations == - nvidia-gpu i2c timeout error at boot: "nvidia-gpu 0000:04:00.3: i2c timeout error e0000000" (USB-C/VirtualLink port) - nvidia-powerd reports unsupported system: "ERROR!
