[Bug 2148266] Re: amdgpu Full System Freeze, Not Reproducible
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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2148266 Title: amdgpu Full System Freeze, Not Reproducible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.17/+bug/2148266/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 2148266] Re: amdgpu Full System Freeze, Not Reproducible
apport information ** Tags added: apport-collected noble ** 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.
