[Bug 2148266] Re: amdgpu Full System Freeze, Not Reproducible

2026-04-20 Thread Rezi Levente
I can confirm a very similar issue on a Lenovo ThinkPad P16s Gen 4 AMD.

System:
- Ubuntu 24.04.3 LTS
- OEM stack active (oem-sutton-daiwa-meta / Lenovo Canonical OEM archive)
- BIOS: R2XET37W (1.17)
- Kernel: 6.17.0-1017-oem

Observed behavior:
- Full system freeze, fan keeps spinning, hard reset required
- Previous-boot journal shows:
  - MES failed to respond to msg=MISC (WAIT_REG_MEM)
  - failed to reg_write_reg_wait
  - MES ring buffer is full
  - hung task warnings

Relevant history:
- linux-image-6.17.0-1017-oem was installed on 2026-04-03 08:35
- older installed kernels still present:
  - 6.17.0-1012-oem
  - 6.14.0-1020-oem

This may be the same regression pattern.

** Description changed:

  Truly grateful for whoever can help
  
  The system experiences intermittent, unrecoverable full system freezes under 
amdgpu on a Lenovo ThinkPad T16 Gen 4 with AMD Ryzen AI 7 PRO 350 (Strix Point) 
and Radeon 860M (DCN 3.5). The freeze is not reproducible even under sustained 
heavy load it occurs unpredictably during light to moderate use (browsing, 
video playback). A hard power button reset is required each time. The keyboard 
becomes unresponsive during the freeze; the mouse cursor remains partially 
active before also freezing or resetting.
  Initial investigation confirmed MES ring buffer overflow as the primary 
cause. Disabling MES (amdgpu.mes=0) resolved the MES errors but the freeze 
persists, now pointing to a separate DCN 3.5 / display scheduler or power state 
transition bug. Runtime PM is reported as unavailable for this GPU.

  • Full system freeze - no input response from keyboard or mouse
  • Mouse cursor occasionally remains active briefly before freezing or 
resetting
  • Keyboard completely unresponsive - Ctrl+Alt+F2 (TTY) and Magic SysRq do 
not work
  • Freeze is intermittent - NOT reproducible under sustained heavy GPU load
  • Occurs during light/moderate use: web browsing, video playback, 
switching tabs
  • System was stable for 1-2 hours before freezing - pattern suggests 
power state transition trigger
  • Hard power button reset required every time
  • No automatic GPU recovery occurs despite lockup timeout parameters 
being set
  • amdgpu Runtime PM reported as unavailable on this hardware
  
  amdgpu.mes=0  Resolved MES ring buffer overflow. No MES errors on subsequent 
boots. Freeze persists.
  amdgpu.sg_display=0   Added as precaution for scatter-gather display issues 
on Strix Point. No observable effect on freeze.
  amdgpu.gpu_recovery=1 Set previously. GPU reset does not trigger — system 
hard freezes before watchdog fires.
  amdgpu.lockup_timeout=1000Set previously. Timeout does not recover system.
  Brave hardware accel  Disabled in browser settings (brave://settings/system). 
Did not prevent freeze.
  X11 instead of WaylandAlready on X11. Wayland ruled out as cause.
  power_dpm_force_performance_level pp_power_profile_mode not available 
(likely due to mes=0). DPM tuning limited.
  linux-firmwareConfirmed up to date. Firmware loads cleanly with no 
errors.
