           Summary: AMDGPU VM_L2_PROTECTION_FAULT causes GPU hang and full
                    system freeze (Firefox/WebRender)

Full dmesg log captured immediately after the AMDGPU VM_L2_PROTECTION_FAULT
freeze.

The system freezes completely when Firefox (WebRender) triggers repeated AMDGPU
VM_L2_PROTECTION_FAULT loops. 
The GPU enters a retry page fault loop and never recovers. The entire system
becomes unresponsive and requires a hard reset.

Hardware:
VGA: Advanced Micro Devices, Inc. [AMD/ATI] Picasso/Raven 2 [Radeon Vega Series
/ Vega Mobile] [1002:15d8] (rev c8)

Kernel:
6.8.0-110-generic

Distribution:
Linux Mint 22.3 (Ubuntu 24.04 base)

Reproduction steps:
1. Start Firefox
2. Open multiple tabs with video or WebGL content
3. Scroll or switch tabs
4. System freezes within 1–5 minutes (intermittent)

Relevant dmesg excerpt:
amdgpu: [gfxhub0] retry page fault (src_id:0 ring:0 vmid:4 pasid:32775, process
firefox-bin)
VM_L2_PROTECTION_FAULT_STATUS:0x00441051
Faulty UTCL2 client ID: TCP (0x8)
PERMISSION_FAULTS: 0x5
RW: 0x1
This sequence repeats in a tight loop until the system freezes.

Full dmesg log can be attached if needed.
