Hi Marc, Thank you for this excellent technical breakdown! Your isolation of the `[gfxhub0] retry page fault` and `VM_L2_PROTECTION_FAULT_STATUS` traces is extremely sharp.
You're completely spot on: while report #2142389 centers around display re-initialization and HDMI EDID handshake failures after power state transitions, your traces point towards a memory page fault under GPU- accelerated workloads (`firefox-bin`). Even though the immediate failure mechanisms differ (Display Core / EDID vs. GFXHUB / GPUVM memory handling), both scenarios highlight how recent kernel cycles have degraded overall stability in the `amdgpu` stack for AMD hardware. It's very plausible that underlying changes in memory management or state transitions in newer kernels are triggering page faults in your case and display link failures in mine. Since both reports demonstrate kernel-level regressions affecting AMD users, building strong community traction across these threads is essential to get the maintainers' attention. If you haven't already, clicking **"Yes, this bug affects me"** on report #2142389 and subscribing to updates would be an awesome way to help us keep the Bug Heat rising! I've subscribed to your report (#2164910) as well and will keep an eye out for any matching GFXHUB/page fault traces in our community logs so we can cross-reference them. Thanks again for the thorough QA work on your logs. Let's keep pushing for driver stability together!
