Port/Peripheral information

Port/Peripheral information

1. USB-C expansion card — DisplayLink dock (Dell D6000 at home / Targus DOCK430 at office; issue reproduces identically with both)
2. USB-A expansion card — Elgato Cam Link 4K (USB 0fd9:007b, UVC capture, used as meeting camera)
3. USB-C expansion card — empty
4. USB-A expansion card — Logitech Unifying Receiver (mouse)

• Peripheral most involved in the crashes: Elgato Cam Link 4K on port 2 (adjacent to the dock on port 1, same left side).
• Framework charger connected through the dock (port 1) during all crashes.
• Note: the dock and the Cam Link both sit on the left side (ports 1-2). Happy to test with the Cam Link moved to port 4 (right side) if useful for isolating a per-side PD/USB controller interaction.

Standalone Operation (Laptop Only)

Are you running your mainboard as a standalone device. Is standalone mode enabled in the BIOS?

• Yes
• [X ] No

Describe the bug

Under WebRTC video conferencing combined with UVC video capture (Google Meet or Slack huddle + Elgato Cam Link 4K), the system either:

• (a) hard-freezes (no SysRq, no logs written, hard power cycle required), or
• (b) freezes then powers off entirely (observed 2026-06-04, three times within 10 minutes — see "crash loop" in Additional context).

Forensic signature matches #206 exactly: journal cuts off mid-line, /sys/fs/pstore empty, /var/crash empty, no MCE/EDAC events, no amdgpu hangcheck/reset logged — the hang happens below the kernel logging layer.

Recurring kernel-log precursor (appears sporadically, minutes-to-hours before crashes, sometimes within 60 s of boot):

amdgpu 0000:c1:00.0: amdgpu: MES failed to respond to msg=MISC (WAIT_REG_MEM)
amdgpu 0000:c1:00.0: amdgpu: failed to reg_write_reg_wait

Chromium-side precursor seconds before several crashes:

ERROR:services/video_capture/video_capture_service_impl.cc:200] Bind context provider failed.

Notably, Chromium's own GPU watchdog has auto-blocklisted the iGPU on this machine (browser GPU process self-starts with --use-gl=disabled despite hardware acceleration enabled in settings) — an independent witness that the GPU stack is unstable.

Frequency before BIOS 3.18: 2-3 crashes/day. After 3.18 (AGESA PhoenixPI 1.2.0.0e): ~1 crash per 2 days — significant but incomplete improvement, consistent with an AGESA/PMFW-class bug. Never crashes when idle or under non-video load (incl. 13 h of memtest86+ at sustained 100 °C, 17 passes, 0 errors).

Related issues: #41 and #58 (same Phoenix 7040 SoC on FW16, same freeze-under-video-load family — this report adds the FW13 data point with a much more frequent, deterministic reproducer), #206 (identical forensic signature and MES involvement on different silicon).

Steps To Reproduce

1. Boot with DisplayLink dock attached (3-4 external displays via evdi).
2. Join a WebRTC video call (Google Meet in Chrome, or Slack huddle) using the Elgato Cam Link 4K as camera.
3. Wait 5-20 minutes.
4. System hard-freezes (sometimes followed by spontaneous power-off).

Crash-loop variant (2026-06-04): after a crash, the browser session-restores and auto-rejoins the call at login, re-triggering the crash within 1-7 minutes — three consecutive freeze-then-power-off cycles (13:34, 13:42, 13:45) until the call tab was closed. See attached crash-loop-logs.txt.

Expected behavior

No freeze or power-off under WebRTC + UVC capture load. Video conferencing with an external capture device is a standard daily workload for this machine.

Relationship to existing issues

• FW16 Freeze then Reboot (FTR) S5_RESET_STATUS = 0x08000800 <- Sync Flood. #41 (FW16 7040, Freeze-then-Reboot / Sync Flood) and FW16 Freeze then Hang (FTH) #58 (FW16 7040, Freeze-then-Hang): same Phoenix 7040 SoC, same freeze-under-video-load family. This report adds the FW13 7040 data point with a much more frequent, deterministic reproducer (WebRTC + UVC capture, ~daily) than FW16 Freeze then Reboot (FTR) S5_RESET_STATUS = 0x08000800 <- Sync Flood. #41's monthly occurrence.
• Framework Desktop (Ryzen AI MAX+ 395 / gfx1151): silent GPU hard hang under sustained compute on stock Ubuntu 26.04 LTS — suspected SMU/MES/PMFW firmware bug #206 (FW Desktop, silent GPU hang, suspected SMU/MES/PMFW): identical forensic signature (journal cut mid-line, empty pstore, hang below logging layer) and same MES involvement, on different silicon — suggesting a firmware-family issue rather than board-specific.

Questions

1. Is a PhoenixPI/AGESA update beyond 1.2.0.0e planned for the FW13 7040 BIOS that addresses MES/SMU hangs under concurrent VCN encode/decode + capture load?
2. Given the deterministic reproducer here (5-20 min, daily), I'm happy to run instrumented builds / collect SMU traces if useful.
