### 🔷 **Issue Summary:** While using Firefox under normal conditions, the system **freezes completely** at random times. The desktop environment becomes unresponsive, requiring a hard reboot to recover. The issue typically occurs during heavier browsing sessions (e.g., video playback or graphics-heavy websites). System logs (`dmesg` and `journalctl`) show **AMDGPU virtual memory protection faults**, indicating a GPU-related issue triggered during Firefox usage. --- ### 🔷 **Log Snippet:** ```text amdgpu 0000:03:00.0: amdgpu: VM_L2_PROTECTION_FAULT_STATUS:0x00641051 Faulty UTCL2 client ID: TCP (0x8) PERMISSION_FAULTS: 0x5 [gfxhub0] retry page fault (src_id:0 ring:0 vmid:6 pasid:32776, for process RDD Process pid XXXX thread firefox-bi:cs0 pid XXXX) ring gfx_low timeout, but soft recovered ``` --- ### 🔷 **System Information:** * **OS:** Linux Mint 22.1 x86\_64 (based on Ubuntu) * **Kernel:** (e.g., `5.15.0-xxx-generic`) ← *replace with actual kernel version* * **CPU:** AMD Ryzen 7 5700U with Radeon Graphics * **GPU:** AMD ATI 03:00.0 Lucienne (integrated) * **Firefox Version:** (e.g., 126.0) ← *replace with actual version* --- ### 🔷 **Steps to Reproduce:** 1. Open Firefox and browse modern websites (YouTube, media-rich content). 2. Use the browser for several minutes (random trigger). 3. Suddenly, the system UI becomes frozen and unusable. 4. Logs show AMDGPU VM fault and `gfx ring timeout`. --- ### 🔷 **Expected Behavior:** System should remain stable during normal browser usage, especially with an officially supported AMD APU. --- ### 🔷 **Actual Behavior:** GPU driver crashes causing total system freeze, likely triggered by hardware acceleration and memory permission faults inside the amdgpu driver stack.
